Making foo italic is pretty easy.
(setq font-lock-defaults
      '((("\\*self\\.\\(\\(?:\\s_\\|\\sw\\)+\\)" 1 my-italic-face))))

But making the reset invisible requires that you put the invisible
property
on the text which requires you to write a function.

For a quick fix you could just make the text invisible by just giving
it a
a face you make with foreground and background the same...

(setq font-lock-defaults
      '((("\\*self\\.\\(\\(?:\\s_\\|\\sw\\)+\\)" 1 my-italic-face)
        ("\\(\\*self\\.\\)\\(?:\\s_\\|\\sw\\)+" 1 my-invisible-face))
       ))

Perhaps someone else has an example of putting properties onto
text under font-lock control....
I don't have one handy.
