Yes, that all seems to work as advertised.  One extra wrinkle was to
preserve the author information by grepping out the last Author: line
from the log.  Here's the work-in-progress version of git-squash (I
don't have a "master" branch, so I stuck in the "mbranch" shell variable
so there is only one place for me to change ... to mbranch=linus).

Any style (or other) comments?  If not I'll package into patch format
with a manual page in a few days.

if [ ! -f .git/refs/heads/"$branch" ]
	die "Can't see branch '$branch'"

if [ -f .git/refs/heads/"$branch"-unsquashed ]
	die "Branch '$branch' has been squashed before"

cp .git/refs/heads/"$branch" .git/refs/heads/"$branch"-unsquashed

git checkout "$branch" || die "Couldn't checkout '$branch'"

git pull . $mbranch || die "Can't merge $mbranch into $branch"

git-rev-list --pretty --no-merges $mbranch..$branch > /tmp/git-squash-$$

git reset --soft $mbranch

author=$(sed -n -e  '/^Author: /s///p' /tmp/git-squash-$$ | tail -1)

git commit --author "$author" -F /tmp/git-squash-$$ -e

rm -f /tmp/git-squash-$$
