From: Phillip Wood <phillip.w...@dunelm.org.uk>
When `rebase -r` finishes it removes any refs under refs/rewritten that
it has created. However if the user aborts or quits the rebase refs are
not removed. This can cause problems for future rebases. For example I
recently wanted to merge a updated version of a topic branch into an
integration branch so ran `rebase -ir` and removed the picks and label
for the topic branch from the todo list so that
merge -C <old-merge> topic
would pick up the new version of topic. Unfortunately
refs/rewritten/topic already existed from a previous rebase that had
been aborted so the rebase just used the old topic, not the new one.
The logic for the non-interactive quit case is changed to ensure
`buf` is always freed.
