Hi, Giorgos,

Thanks for all the explanation!

OK, that's quite likely.  Am I right believing that 'bzr merge' pulls in
any changes in the current branch's parent?

Do I want to revert it?  I don't think I do.  If I just do "bzr commit"
in my .../quickfixes, that should leave it in a consistent state,
shouldn't it? 

After that, I want to get my changes from .../quickfixes copied over to
.../trunk.  Is 'bzr push' the way to do this?
