As long as your changes are based off the tag-changeset, they'll still all be in one branch rather than creating a new head. > - If it's ok, should I file an RFE for Mercurial to allow me to > specify the changeset which creates a given tag?

The trickier part I recall is that you could conceivably diverge where onnv_79 is the divergence point and have multiple branches from there. So "+1" is hard to define in that scenario. Again though, the policy for onnv-gate was to never grow a second head - so the strictly linear nature means +1 should never be unambiguous.
