It's rather something I tend to do by accident.  I start a command in
frame F1 which uses the minibuffer, I swap to F2 to look for the text I
want to enter in F1, then sometimes forget I've got the command in F1
still active.

Above all, I want the command in F2 to use the echo area of F2, not that
of F1 (which in my TTY setup is not visible).

I'm not understanding that, properly.  When I enter characters into
isearch in F2, this doesn't throw an error when the F1 minibuffer is
still active.  Is isearch perhaps just using the echo area, here?

Anyway, I tried the suggestion of Gregory Heytings from yesterday evening
at 21:48:49 +0000.  He put an extra condition into
set-minibuffer-message, so that it only does its thing when the current
frame is also the minibuffer's frame.  It appears to work well.
