Hmm, are we sure that this is a "feature"? The most common use for
greek symbols is in equation and the most common word processor for R
users is (hopefully/probably/maybe) LaTeX ... and greek letters in
LaTeX equations are italic ... hence shouldn't we make them available
(if possible)?

But I must admit that I obviously didn't need it before ... :-)
