Allow restriction to "current branch" while keeping graph topology intact

[mlange-42]

Problem: when walking the respository from HEAD, back-tracing of branches does notwork properly.

Solution: back-trace the entire graph, but display only what is reachable from HEAD

Hello there! I'd like a similar idea, but more expanded:

Allow a vararg listing of refspecs, and visualize all n-1 refspecs with regards to the merge-base of the 1st refspec.
Or, in lay-mans terms: I have a main and two branches that were incrementally merged to main. I'd like the subgraph that tracs merge-base of all of the aforementioned refspecs on the bottomo, the origin/main on top, and in-between the paths that those branches create with regards to main.

Would this be tracked here, or should I create a separate issue for it?

@stdedos You could well make a separate issue for it, to avoid that it gets lost. Also, I think some graphical/ascii art illustration would help to understand your proposal.
