(Right, apologies for the attitude.  I was annoyed with myself for
diluting the help-echo problem by suggesting unrelated changes to the
'symbol and 'text representations of warnings-suppress, and got worried
that the former would go unaddressed.  Wish I had been less heavy-handed
in that parenthetical)

One concern I have with (b): might some clients rely on the current
behavior?  An unconditional fallback would force them to remove that
text property themselves.

I do not deal with buttons much so no intuition on existing practice; I
could see an argument for either behavior - "better some help message
than none" vs "better no help message than the wrong help message".

ACK to improve buttonize-region too.  button--properties does not have
access to the information needed to get the fallback help-echo tho
(STRING for buttonize, START END for buttonize-region), are you thinking
of passing that fallback as a new argument, or have I missed something?
