[Rpm-ecosystem] Rich deps syntax finalization

[Florian Festi]

My thought after the discussion so far:

May be no one really cares about the syntax.
Still a lot of educating to do before rich deps go into production.

Guess we stay with (. IF . ELSE .) - even some people are more familiar
with (. ? . : .).

I am now tending to actually *use lower case*. This is what most
programming languages do. May be familiarity beats emphasizing the
operators with CAPS.

So (. if . else .)

I think we go for "and" and "or" for consistency. In the end it is
really close with | and & to stay with dpkg. What pushed it over to and,
or was having a different but consistent style for the rich deps - in
opposite to macros and version comparisons.

NOT is confusing people and they have problems coming up with real use
cases. So we will go without for now and reconsider when real need arises.

Speak now or forever hold your peace.
