Thanks for enlightening me about this. I thought sed was greedy with
address spaces the same way it's greedy with regex.

    sed -e '/^# Please enter the commit message /,/^#$/d'


This command does seem to work regardless of the cleanup mode used.

That said, in case my interpretation that "'prepare-commit-msg' hook is
not to be shipped due to it's uselessness" is correct, the reply of
this mail as a whole seems to contradict it.

Should I work on this patch and another related one (he one that
modifies the signature part of the hook) or
should I drop it ?

IOW, would this patch likely make the hook useful again?
