Right, that part's simple.

One problem is that emacs allows faces to have `device dependent'
definitions, for cases where the most general definition isn't emulated
well.  A fair number of emacs' standard faces have `tty-specific'
definitions, and some of these might assume that ttys never have italic
(bold's probably not a problem, since ttys already sort-of support bold
via intensity).

I recently added capability-testing support (the `supports' clause) to
the face code so any faces that make that assumption about ttys could be
changed to directly test for italic support instead.

[In general I think the above isn't really a problem, since most
`tty-dependent' face definitions actually care about the color depth
(though this is another thing that should be changed to use a
capability-testing model instead).]
