I don't recall this stuff well, but as far as I remember, the facility
didn't seem to be used anywhere -- I guess I didn't look hard enough
-- and was completely undocumented.  Is there doc for this?  What is
supposed to happen and what would be necessary for XEmacs
compatibility?  I seem to remember that some basic things are
incompatible for one reason or another.  I don't remember whether
we've used :help-echo functions anywhere in Emacs 21.

I'm not sure exactly what this means to implement:

(Why) should that be different from the button code?

I agree documentation should exist.  The widget doc has had work done
but doubtless needs more -- I know I've had trouble writing widget
code.  If this does merit a NEWS entry, presumably other additions to
the wid-edit do too, specifically the image stuff which is probably
also incompatible...  Guidance welcome.
