Well, the revision should be an integer. But (I think) it's best to
not try to match it at all; is it needed for something?
Untested:
LC_ALL=C
/^(([0-9]+):)?([a-zA-Z0-9.+:-]+)(-([a-zA-Z0-9.+]+))?$/ || die
debianrevision=$2 # or unset
upstreamver=$3
debianrev=$5 # or unset
This is simpler without splitting out the revision.
