Problem: some errors with translation Makefiles
Solution: fix issues
Update src/po/ makefiles after 9.0.2127
* Change how to check `%LANGUAGE%`.
Check it only when needed.
* Add double quotes to where `GETTEXT_PATH` is used.
Before 9.0.2127, this worked: `nmake -f Make_mvc.mak GETTEXT_PATH="\"C:\Program Files\Git\usr\bin\""` (which was a bit tricky.)
9.0.2127 broke this and syntax error occurred.
This doesn't work either in 9.0.2127: `nmake -f Make_mvc.mak GETTEXT_PATH="C:\Program Files\Git\usr\bin"`
With this Commit, this works: `nmake -f Make_mvc.mak GETTEXT_PATH="C:\Program Files\Git\usr\bin"`
* Better error report for the `check` target.
Show the line number of the error. (Imported from vim-jp/lang-ja.)

closes: #13571
This Commit fixes a SEGV caused by a use-after-free bug in call_dfunc().
When calling check_ufunc_arg_types() from the call_dfunc() it may cause
def functions to be re-compiled and if there are too many def functions,
the def_functions array will be re-allocated. Which means, that the
dfunc pointer in call_dfunc() now starts pointing to freed memory.
So we need to reset the dfunc pointer after calling
check_ufunc_arg_types().

patch 9.0.2123: Problem with initializing the length of range() lists
Problem: Problem with initializing the length of range() lists
Solution: Set length explicitly when it shouldn't contain any items
range() may cause a wrong calculation of list length, which may later
then cause a segfault in list_find(). This is usually not a problem,
because range_list_materialize() calculates the length, when it
materializes the list.
In addition, in list_find() when the length of the range was wrongly
initialized, it may seem to be valid, so the check for list index
out-of-bounds will not be true, because it is called before the list is
actually materialized. And so we may eventually try to access a null
pointer, causing a segfault.
So this patch does 3 things:
- In f_range(), when we know that the list should be empty, explicitly
set the list->lv_len value to zero. This should happen, when
start is larger than end (in case the stride is positive) or
end is larger than start when the stride is negative.
This should fix the underlying issue properly. However,
- as a safety measure, let's check that the requested index is not
out of range one more time, after the list has been materialized
and return NULL in case it suddenly is.
- add a few more tests to verify the behaviour.

patch 9.0.2122: [security]: prevent overflow in indenting
Problem: [security]: prevent overflow in indenting
Solution: use long long and remove cast to (int)
The shiftwidth option values are defined as being long. However, when
calculating the actual amount of indent, we cast down to (int), which
may cause the shiftwidth value to become negative and later it may even
cause Vim to try to allocate a huge amount of memory.
We already use long and long long variable types to calculate the indent
(and detect possible overflows), so the cast to (int) seems superfluous
and can be safely removed. So let's just remove the (int) cast and
calculate the indent using longs.
Additionally, the 'shiftwidth' option value is also used when determining
the actual 'cino' options. There it can again cause another overflow, so
make sure it is safe in parse_cino() as well.
patch 9.0.2121: [security]: use-after-free in ex_substitute
Problem: [security]: use-after-free in ex_substitute
Solution: always allocate memory
closes: #13552
A recursive :substitute command could cause a heap-use-after free in Vim
(CVE-2023-48706).
The whole reproducible test is a bit tricky, I can only reproduce this
reliably when no previous substitution command has been used yet
(which is the reason, the test needs to run as first one in the
test_substitute.vim file) and as a combination of the `:~` command
together with a :s command that contains the special substitution atom `~\=`
which will make use of a sub-replace special atom and calls a vim script
function.
There was a comment in the existing :s code, that already makes the
`sub` variable allocate memory so that a recursive :s call won't be able
to cause any issues here, so this was known as a potential problem
already. But for the current test-case that one does not work, because
the substitution does not start with `\=` but with `~\=` (and since
there does not yet exist a previous substitution atom, Vim will simply
increment the `sub` pointer (which then was not allocated dynamically)
and later one happily use a sub-replace special expression (which could
then free the `sub` var).
The following commit fixes this, by making the sub var always using
allocated memory, which also means we need to free the pointer whenever
we leave the function. Since sub is now always an allocated variable,
we also do no longer need the sub_copy variable anymore, since this one
was used to indicated when sub pointed to allocated memory (and had
therefore to be freed on exit) and when not.

space is shown.
Also, you may find that the filesize of the multibyte named file is not

Now we have 32 + 2 + 15 = 49 characters for filename and filesize.
It tries to align the filesize as much as possible.
The last line that has multibyte filename is also aligned.

Problem: crash when callback function aborts because of recursiveness
Solution: correctly initialize rettv
Initialize rettv in invoke_popup_callback()
Since v9.0.2030, call_callback may exit early when the callback recurses
too much. This meant that call_func, which would set rettv->v_type =

Without rettv->v_type being explicitly set, it still contained whatever
garbage was used to initialize the stack value in invoke_popup_callback.
This would lead to possible crashes when calling clear_tv(&rettv).
Rather than rely on action at a distance, explicitly initialize rettv's
type to VAR_UNKNOWN so clear_tv can tell nothing needs to be done.

patch 9.0.2112: [security]: overflow in shift_line
Problem: [security]: overflow in shift_line
Solution: allow a max indent of INT_MAX
[security]: overflow in shift_line
When shifting lines in operator pending mode and using a very large
value, we may overflow the size of integer. Fix this by using a long
variable, testing if the result would be larger than INT_MAX and if so,
indent by INT_MAX value.
Special case: We cannot use long here, since on 32bit architectures (or
on Windows?), it typically cannot take larger values than a plain int,
so we have to use long long count, decide whether the resulting
multiplication of the shiftwidth value * amount is larger than INT_MAX
and if so, we will store INT_MAX as possible larges value in the long
long count variable.
Then we can safely cast it back to int when calling the functions to set
the indent (set_indent() or change_indent()). So this should be safe.
Add a test that when using a huge value in operator pending mode for
shifting, we will shift by INT_MAX

so the initial test using :s/./b/9999999999999999999999999990 doesn't
fail there, since the count is wrapping around several times and finally

The problem is the name of the current filetype wast. When the plugin

However, recently .wat became the official file extension for

to describe the Wasm specification conformance tests.

extension, so that we at least do not lose the filetype settings and

patch 9.0.2103: recursive callback may cause issues on some archs

patch 9.0.2095: statusline may look different than expected
Problem: statusline may look different than expected
Solution: do not check for highlighting of stl and stlnc characters
statusline fillchar may be different than expected
If the highlighting group for the statusline for the current window
|hl-StatusLine| or the non-current window |hl-StatusLineNC| are cleared
(or do not differ from each other), than Vim will use the hard-coded
fallback values '^' (for the non-current windows) or '=' (for the
current window). I believe this was done, to make sure the statusline
will always be visible and be distinguishable from the rest of the
window.
However, this may be unexpected, if a user explicitly defined those
fillchar characters just to notice that those values are then not used
by Vim.
So, let's assume users know what they are doing and just always return
the configured stl and stlnc values. And if they want the statusline to
be non-distinguishable from the rest of the window space, so be it. It
is their responsibility and Vim shall not know better what to use.
Do not rely on the fact, that the last line matches warning, error,
inappropriate or unrecognized to determine if an error occurred. It
could also be a file, contains such a keyword.
So make the error detection slightly more strict and only assume an
error occured, if in addition to those 4 keywords, also a space matches
(this assumes the error message contains a space), which luckily on Unix
not many files match by default.
The whole if condition seems however slightly dubious. In case an error
happened, this would probably already be caught in the previous if
statement, since this checks for the return code of the tar program.
There may however be tar implementations, that do not set the exit code
for some kind of error (but print an error message)? But let's keep this
check for now, not many people have noticed this behaviour until now, so
it seems to work reasonably well anyhow.
