Are hex numbers allowed in version names?
I think the best rev number is something like:

<last version tag>.<number of descendants>-<nodeid>

I.e. for 9f9bbd33f71e, it would be:
1.1.2.7712-9f9bbd33f71e

<number of descendants> might be different from the rev number, if the
cset isn't tip, or if it's a multi-head repo. It can be seen as the
smallest possible rev number for a given cset.
