We would need a copyright assignment from you to work on this.  I'll
send you the request form in separate mail.

Well... if you can expend the time, it would be nice if you created
minimal test cases (the Emacs icon is useful for that since it comes
with Emacs) and reported them to the Emacs developer list: while it is
nice if workarounds for released Emacs versions can be found, one
would not want the bugs to persist.

Yes.

If we adopt this, I'll likely do that.  While AUCTeX does load cl when
compiling, I actually doubt that it is necessary for pretty much
anything by now.  We should perhaps try throwing it out and see what
happens.

XEmacs' balloon help never got to a state where sane people would want
to enable it, anyhow.  At least that was the state in the 21.4
versions I have seen, and I doubt it progressed beyond it,
