Okay, here's my next proposal: The tab-line-tab-face-default function
returns a face, and then a new option, tab-line-tab-face-modifiers, is a
list of functions, each of which is called with that face and returns
it, possibly modified. This seems like a flexible mechanism which makes
it possible to modify the faces orthogonally according to arbitrary
criteria, and it can be used to add the alternating colors and
special-buffer faces when applicable (when so-configured by the user).
It could also be used to do a "rainbow" of faces, as you mentioned, etc.
To address Eli's feedback, in this patch I also defined the alternate
face to have a certain background color by default rather than
inheriting from mode-line.
However, the issue regarding italic slant on terminals remains; I'll be
glad to do whatever you or Eli suggest.
Thanks to you and Eli for your help.
