Subject: Make rebase script saner.
X-Git-Tag: v0.99.5~15^2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/99a92f928fd02a87d841a8bb19511e7ce526819d

Make rebase script saner.

It did not check to see if the working tree was clean and matched
the commit we were starting out as, resulting in the initial rebased
commit including whatever dirty state the working tree has had.
