Yes, all my branches are bound. Just like `merge', it only operates on
the checkout anyway, so it shouldn't make any difference whether it's
bound or not.

Yes, it should only stop when it encounters conflicts.

That's the intention.

You can do that as well. Either should work.

Currently, no. But you can easily tweak the code to change the regexp
so it matches all commits.

I think it depends on the particular case. When I've had to do that
(e.g. a change in tramp.el which moved to tramp-sh.el) bzrmerge
signaled a conflict and I resolved it by hand (by applying the failed
patch to the other file) and then updated the ChangeLog comment to say
But if the resolution ends up with completely different code, I think it
makes sense to commit it as a new change rather than as a merge of some
The one important thing is to make sure we don't drop changes, so it's
better to first commit a new solution on the trunk, and then merge the
old solution (and just resolve the conflict by leaving the code
unchanged), rather than merge first and then install
a different solution. Sadly, this is sometimes inconvenient: I may
want/need to merge *now* because I want to install something that
depends on an yet-unmerged change and then bump into a conflict in
someone else's code, at which point you may find you prefer drop his
change so you can go on with yours and hope he won't forget to install
an updated solution.
