PREFIX hack: a revision starting with 0 is an 'inter-revision',

PREFIX hack: a revision starting with 0 is an 'inter-revision',
which means that it is possible to create revisions on revisions.
An example is -r01.1 which is the first revision of -r1.  Note
that a period (.) is used to separate the real revision and the
secondary revision number.  This trick is in use to allow revision
bumps in ebuilds synced from the main tree for prefix changes,
while still staying in the main tree versioning scheme.
