OTOH which echo-area message goes through `message` and which goes
through some lower-level C function is largely an implementation detail
(e.g. in order to know that uncaught errors get displayed without going
through `message` the user has to read the C code, AFAICT), so I think
it makes sense to try and make sure we go through `set-message-function`
whenever possible.
