PORTVERSION and portlint

[Sergey Matveychuk]

What's wrong with '+' sign in PORTVERSION?
www/apache13+modssl, russian/apache* and dns/bind9-dlz ports use it for 
separating port version and module version. I think it's a good practice.

But portlint marks it as FATAL. May be make a sense this simple patch to 
apply?
