Two comments and a half.

This patch does not make things worse, so I do not have much against it.

However, "sed -i $cmd" is also used in templates/hooks--prepare-commit-msg
and you would want to fix it as well.

But more importantly, as we are serious about portability, we should not
be using "sed -i" which is not even in POSIX to begin with.  Can we
rewrite these places without using the in-place extension?
