Is there no way to extract the message from the message produced by
git format-patch?

For example, if I look at a typical patch file, it starts:

>From 5def4c0b997293ebdcd2e1b9268e613d2bac65cb Mon Sep 17 00:00:00 2001

So, as a rough attempt:

#!/bin/sh
# git-format-patch-to-changelog
# Extract a changelog entry from a git format-patch file
GIT_PATCHFILE=$1
TEMPFILE=`mktemp`
agrep -d '^---' Subject $GIT_PATCHFILE > $TEMPFILE
echo `grep "^Subject:" $TEMPFILE | sed -e 's/.*\] //'`
grep -v "^[[:alpha:]]" $TEMPFILE

Or perhaps you have a better suggestion for integrating it into one's
git workflow in a way that one is prompted to write the ChangeLog
entry?
