Too late, the function must be redefined before the first prompt is
sent.  I thought it would be simpler to give you the rewritten defun
separately instead of having you patching ansi-color.el ;-)

Yes.  As you found out in your original report the prompt coloring has
been broken for longer.  If you customize the comint-highlight-prompt
face so that it doesn't inherit from minibuffer-prompt (which does the
blue colouring), you'll see that the current prompt is actually coloured
correctly but for the previous prompts, comint-highlight-prompt just
replaces the ansi-color faces.  That's weird.  Somebody should at some
point do something about it ;-)

In any case, you submitted a separate report about the prompt issue,
viz. bug#11883.

So, I'd say that the issue at hand is solved.  I'll just try to rewrite
the new ansi-color-apply-sequence in a less ugly way.
