"git diff" has a --check option that can be used to check for

The primary use of this option used to be to see where the breakages
are
in order to fix them up (IOW, the option was not about seeing if
breakage exists or not), but that is much easier with --color output
these days.
It is probably a good idea to do this, although I do not care much
about
it either way. It probably could replace the sample pre-commit hook
currently implemented in Perl.
Actually, that's exactly why I prepared this patch; I was looking at
the pre-commit hook and though, surely there must be a simpler way
than this... And was surprised when I saw that "git diff --check"
didn't alter the exit code...
As I happen to be fairly familiar with
the area, I'll take a look at the patch if/when I find time.
Thanks. I'm about to resend this patch with more tests, and one fix
discovered while adding the tests ("git diff-tree" was only setting
the exit status with --stdin set), as well as a new version of the pre-
commit hook.
One nice thing about this change is that when "diff --check" learns
about the new core.whitespace stuff, the hook will automatically
inherit the new behaviour.
Cheers,
Wincent
