Re: Unexpected behavior when git-adding files in a pre-commit hook then using "git commit -o"

As pre-commit is a verification (and rejection) mechanism, not a
mechanism to tweak what is to be commited, it is totally expected
that its behaviour is unspecified when you modify anything in it.

I think I saw a similar confusion posted to the list once in the
past few years.  Perhaps we would need a documentation patch to
clarify this.

Thanks.
