[AUCTeX] preview equations in reftex-reference

[Andreas Matthias]

This is just a thought about something that would simplify
my work even more.

I prefer to use reftex-reference to insert references. However
it is still cumbersome to find the right equation in a long
list of equations. It would be marvelous if equations were
previewed in RefTeX Select Buffer (M-x reftex-reference)
as well.

Maybe this is worth an item in your, definitely not short,
TODO list?
