[PATCH 0/3] builtin-commit fixes

A little series to bring built-in commit back in line with the behaviour as implemented by git-commit.sh and described in the documentation.

1/3 Allow --no-verify to bypass commit-msg hook

- git-commit.sh used to do this, but builtin-commit wasn't.

2/3 Documentation: fix --no-verify documentation for "git commit"

- The "git commit" man page should mention the commit-msg hook to
bring it in line with what's in the hook notes and in
Documentation/hooks.txt.

3/3 Fix commit-msg hook to allow editing

- Again, git-commit.sh allowed this, but builtin-commit wasn't
doing so.

I have manually tested these changes and they seem to work, but the fact that the test suite didn't break when the behaviour of "git commit" changed is indicative of a hole in the suite. I am not very familiar yet with the test machinery, but I am going to see if I can whip something up.

Cheers, Wincent
