Thanks, Martin,

The LimeGreen is showing up and the "sp?" inside of "(sp?)".  I'm
thinking that the "()" chars are being overwritten by other, blue
highlighting.  I changed the last line above to:

    ("\\<\\(XXX\\|xxx\\)\\>\\|\\_<\\(\\?\\?\\?\\)\\_>\\|(\\(sp\\?\\))" .
'my-extra-face)))

because I don't want the last three chars of "What's lisp?" to be
highlighted, but only "(sp?)".  So all of that is fine.

However, "???" is not being highlighted.  There's a lot of characters
clustered around the "???"... I'm wondering if they're all supposed to
be there....

Again, I just want ??? to be highlighted, not _<(???)>_ or anything like
that... just "???".


Thanks for any solutions.
