Ah, thanks, I now vaguely recall seeing these but forgot about them.
They indeed do work just as well as my proposed change to
set-transient-map for text-scale-adjust as well as two private functions
I use that pass a message string matching the same regexp, so that
satisfies my immediate wish.  Still, there could be any number of
callers of set-transient-map that pass message strings users may want to
suppress but that require a different regexp, in which case the burden
on the user is more than with my patch.  But since that's AFAIK
currently only a theoretical possibility, I won't pursue the proposal.
I'll wait a few days in case someone does chime in favor of my patch,
but otherwise I'll then close the bug.
