[Fedora-packaging] forbid fedora or redhat in spec files?

[Patrice Dumas]

Hello,

I have seen people saying that we should avoid using 'fedora' and 'redhat'
in spec files, to help reusing in other contexts (be it, selfishly,
EPEL/RHEL/OLPC, or other distros or upstreams). I think it is a good
idea, especially since there is a trademark on fedora and redhat (unless 
I am wrong).

Should we have a guideline about that? Or on a 'trick' page?
