Personally, I'd set PORTREVISION to 100 in the branch and merge often. Who
says that
the first bump has to be to 1? If you really want it to be the numerically
next number, bump
it each time there's a conflict, (so 101, 102, 103) then you can look for
those > 100 and
re-adjust. If this has been done before, start at 200, etc. Since there's
nothing wrong with 100,
though, you could do this and land it like that in the main tree.

It's a different variation on the force a conflict ploy though
