maint: choose editor in the commit-msg git hook the same way git does
Git honours the GIT_EDITOR environment variable, the "core.editor" Git
configuration variable, and the EDITOR environment variable (in that
order, and defaulting to "vi" if none of them is set) to decide which
editor should be invoked for the user when he has to or want to edit
his commit message.
However, our commit-msg hook, when invoking an editor on behalf of the
user to allow him to fix a non-policy-complaint commit message, only
honoured the EDITOR environment variable. To avoid potential annoying
inconsistencies, we should really use the same logic used by Git in the
selection of the editor. Luckily, we don't have to duplicate this
logic (that would be brittle in the long term), as we can rely on the
"git var" command, designed exactly to be used in situations like this.
maint: don't reset PATH in the commit-msg git hook
I have a custom 'editor' script in ~/bin, and a system-provided
'editor' program in /usr/bin (on Debian, this is a link set up the
"debian alternatives" subsystem). My '$EDITOR' and '$GIT_EDITOR'
variables are set simply to 'editor' (no absolute path), which I
expect should point to my 'editor' script, since ~/bin precedes
/usr/bin in my PATH definition. But the 'commit-msg' hook used in
coreutils unconditionally resets its PATH to '/bin:/usr/bin', which
causes it to call the "wrong" editor (the one in /usr/bin, not the
one in ~/bin) when it makes me update a botched commit message.
* scripts/git-hooks: Don't reset $ENV{PATH} to '/bin:/usr/bin',

factor: apply a more general fix to enable correct assembly
In addition to the previous 64 bit guards we've placed in longlong.h
there are additional _LP64 guards required for mips with -mcpu >= 3,
to avoid a build failure (http://bugs.gnu.org/13353) and on sparc
with -mcpu >= v9 in 32 bit mode where for example,
`factor 2123123123123123123123` would go into an infinite loop.
Since factor.c currently operates on uintmax_t, we restrict the use
of the assembly in longlong.h to when 'long' has the same width, to
provide a more general guard for this code.
* src/factor.c: Restrict the use of longlong.h assembly code,
to when the width of intmax_t == long.
* src/longlong.h: Remove the previous _LP64 guards to avoid
divergence from GMP's longlong.h
* NEWS: Adjust the info on build and runtime fixes.
