All you forgot was to explain how repo-id helps one iota.   And if you're
up to it, explain how it would help sort out the following, where Xn is a
fast forward head:

Rn   o
     > \
Rn-1 o  |
     >  o Mn
     >  o Mn-1
Rn-2 o /
Xn   o

And what about sorting out branches created by a single developer in a
single repository? doh!   Sounds like a solution that addresses all these
should be worked out instead of repoid.   You really are barking up the
wrong tree here.

Just because rev-tree may get it wrong, doesn't mean every other tool does.
Actually, I just ran your above scenario through git, and here is what
cg-log shows, which seems perfectly acceptable:

In fact, please see attached .png image that shows how the nice gitk tool
from Paul Mackerras displays it exactly as you request WITHOUT Repo-id.

* Please * explain what problem you are trying to solve and how repoid
will solve it.
