CONFLICTS usage question

[Yar Tikhiy]

Hi folks,

Is it all right if a wildcard pattern listed in CONFLICTS
matches the port's package itself?  Here's why I'm asking:
There is a port "mail/bogofilter" that has 2 child ports,
"mail/bogofilter-qdbm" and "mail/bogofilter-tdb".  I'm about
to add the 3rd child port for it, "russian/ru-bogofilter".
Presently, the existing ports cross-list each other in CONFLICTS.
It seems easier to have a single CONFLICTS setting, in the master
port, that reads:

CONFLICTS=	bogofilter-* [a-z][a-z]-bogofilter-*

Will that be legal in our ports framework?
