port naming question

[Eitan Adler]

One of the ports I maintain (allegro) has three branches
4.2.* == main branch
4.3.* == development branch
4.9.* == the future 5.0

1) I want to make a 4.9 port - but the version number isn't yet 5.0. Is
it appropriate to call the port allegro5 and just use the 4.9 version
number for now?
2) How do I tell portscout to ignore 4.9.* in the allegro-devel branch?
