Re: DEVEL: Help with feature implementation

Hi Antonio and Derrick!

I think what you really want is --full-history --simplify-merges [1]. This
will show the merges that "fork" the history into parallel tracks where
at least two of them contain interesting commits.

It doesn't look like the implementation of --simplify-merges helps much
here. That makes its decision on basis of the parents of the commit, which is
simple to do as it's information attached freely to each commit. I think the
problem here would be figuring out, given any commit, how many of its children
are "relevant" commits.

I'm actually working on something that does the opposite---it ignores
the fork point when drawing the graph.  (I'm currently dog-fooding a
partial implementation of this.)

That's a pretty interesting coincidence :)

Just to throw ideas out there, maybe we could attach another commit_list,
children, to the commit metadata, so that all this becomes a little easier.
But I guess that's be pretty impractical and inefficient.

Maybe a more practical (but still pretty unusual) solution would be adding
counters to each commit that tell us how many times they have been traversed
Through various histories?
