So the difference is that what you want to see is all the branches up
to their HEAD, and not just branches merged into the current branch,
is that right?

If so, I guess some optional feature of "C-x v L" could do that.
However, if the repository has many branches (and ours, for example,
does), wouldn't that make for a crowded and hard-t-read log buffer?
Perhaps asking the user for a name of one branch will be enough?  More
than one branch could be problematic on display, I think.
