rebase: backed out changeset cf8ad0e6c0e4 (issue5610)
Having a single transaction for rebase means the whole transaction gets rolled back
on error. To work around this a small hack has been added to detect merge
conflict and commit the work done so far before exiting. This hack works because
there is nothing transaction related going on during the merge phase.
However, if a hook blocks the rebase to create a changeset, it is too late to commit the
work done in the transaction before the problematic changeset was created. This
leads to the whole rebase so far being rolled back. Losing merge resolution and
other work in the process. (note: rebase state will be fully lost too).
Since issue5610 is a pretty serious regression and the next stable release is a
couple day away, we are taking the backout route until we can figure out
something better to do.
