Re: [PATCH] git-commit: exit non-zero if we fail to commit the index

Shouldn't we be doing this? I think if quiet is set,
then a failed rename will go undetected since we
won't enter print_summary to have lookup_commit fail.

But then it's a bit too late, isn't it?  We already have
successfully made the commit and updated the HEAD to point at
it.  We would need to tell the user that the index is not where
it is when we detect the error, though.

run_hook also is not checked for failure.

I think you mean the final post-commit one, but that is
deliberate.  post-commit is not meant to affect the outcome of
the command.
