I think that we should consider restricting revisions to 4 digits.
Real revisions (i.e., counted up from r0) in the tree seem to end
somewhere around r30. Even with r100, r200 for different slots, a
limit of 9999 shouldn't pose any problems. For date based versions,
_pre or _p should be used, but not revisions.

Note that this would be tree policy only (similar as the maximum
length of 18 digits for version components is), but _not_ a
restriction to be put in PMS.

Or rules concerning multiple suffixes are simple and straight forward,
and they don't appear to be abused. Therefore, I would leave them
alone.
