We've discussed yesterday at #mercurial another idea which I've implemented as
an extension:

http://hg.piranha.org.ua/branchspec/

It returns range of revisions which form branch, ending with supplied head by
using "hg log -r #head" syntax.

I guess this is quite ad-hoc for your taste too, but I have nothing better in
mind yet - but if you (or anybody else) do, I'd be happy to explore
possibilities and write code.
