The comment at the beginning of the script documents most hooks.*
configuration options[1], so please document this one as well.

This seems excessively harsh, as it would block commits where
@localhost appears in the diff[2] or is used in the commit message
in a legitimate way[3].
We need to either be way more specific in selecting the parts of
the commit we care about (Author:, Commit:, Signed-off-by: and
Reviewed-by: at the very least) or replace the match with something
like
grep -E '<.*(a)localhost.*>'
which I think should catch most plausible mistakes without running
into false positives.
[1] hooks.allowmissingsob is notably missing, perhaps whoever
introduced it should go back and document it ;)

could argue that such a commit would not have been necessary if
we had this hook in the first place O:-)
