difftool: don't overwrite modified files
After running the user's diff tool, git-difftool will copy any files
that differ between the working tree and the temporary tree. This is
useful when the user edits the file in their diff tool but is wrong if
they edit the working tree file while examining the diff.
Instead of copying unconditionally when the files differ, create and
index from the working tree files and only copy the temporary file back
if it was modified and the working tree file was not. If both files
have been modified, print a warning and exit with an error.
Note that we cannot use an existing index in git-difftool since those
contain the modified files that need to be checked out but here we are
looking at those files which are copied from the working tree and not
checked out. These are precisely the files which are not in the
existing indices.

wt-status: fix possible use of uninitialized variable
In wt_status_print_change_data, we accept a change_type flag
that is meant to be either WT_STATUS_UPDATED or
WT_STATUS_CHANGED. We then switch() on this value to set
the local variable "status" for each case, but do not
provide a fallback "default" label to the switch statement.
As a result, the compiler realizes that "status" might be
unset, and complains with a warning. To silence this
warning, we use the "int status = status" trick. This is
correct with the current code, as all callers provide one of
the two expected change_type flags. However, it's also a
maintenance trap, as there is nothing to prevent future
callers from passing another flag, nor to document this
assumption.
Instead of using the "x = x" hack, let's handle the default
case in the switch() statement with a die("BUG"). That tells
the compiler and any readers of the code exactly what the
function's input assumptions are.
We could also convert the flag to an enum, which would
provide a compile-time check on the function input. However,
since these flags are part of a larger enum, that would make
the code unnecessarily complex (we would have to make a new
enum with just the two flags, and then convert it to the old
enum for passing to sub-functions).

fast-import: clarify "inline" logic in file_change_m
When we read a fast-import line like:
M 100644 :1 foo.c
we point the local object_entry variable "oe" to the object
named by the mark ":1". When the input uses the "inline"
construct, however, we do not have such an object_entry.
The current code is careful not to access "oe" in the inline
case, but we can make the assumption even more obvious (and
catch violations of it) by setting oe to NULL and adding a
comment. As a bonus, this also squelches an over-zealous gcc
-Wuninitialized warning, which means we can drop the "oe =
oe" initialization hack.
