Well, I have do nothing but experiment with my branches. So I try to
access to old backups of my main branch, but I miss one revision from
today. So I try to make branch from mixed main branch (that I pull by
mistake) and try to run 'bzr branch -r revid:XXXX' and hopefully it
works OK. After that I have restored main branch and I can do merge as
you suggested.

This is not trivial operation but I'm cope with this task :-)
May be it need to write something like a receipe about how to deal with
this situation.

I'm glad to certain in practice that my history actually don't lost,
just slightly harder to access to particular non-mainline point. I guess
  GUI should do this operations more easy.
