Renaming Conditional.pm and ConditionalSet.pm... to what?

[Alexandre Duret-Lutz]

We need to rename Conditional.pm and ConditionalSet.pm for the
sake of 8+3 file systems, and as I'm very bad (see below) at
naming thing I'm asking for ideas.

Besides changing these class/file names, it would be nice to
settle on the vocabulary we use to designate various
conditonal-related concepts.  For instance presently we say that
AM_CONDITIONAL defines 'a conditional', but this is different
from the concept represented by the Conditional class.  The
latter is defined as `a conjunction of atomic conditions', where
`atomic condition' is just another way to designate the former...

For this reason I'd prefer not renaming these files to Cond.pm
and CondSet.pm.  Maybe CondConj.pm and CondDisj.pm?  (The latter
would be more accuratelly named CondConjDisj.pm but that would
conflict on 8+3 file systems.)
