OK, so let's go with your suggestion, but make that message we agreed
should be added say something like

  ElDoc mode echo-area display turned off; type .... to turn on

where "..." stands for whatever needs to be done to turn it back on
again.

Also, I do think a defcustom is due instead of a hardwired constant of
1 sec.

Could you please augment your patch along these lines?

Thanks.
