bug#57664: 29.0.50; echo area display

[Richard Stallman]

When I send an email with Mail mode, it actually writes the email into
a file.  (Later I will transfer that file to a server and send it out
for real.)  There are multiple calls to `message' in that path, and in some
cases they include the line

  Wrote /home/rms/outgoing/out-13

followed by

  Already 5

With last April's sources, the "Already" replaced the "wrote" message.
But now it increases the echo area to two lines.

What change causes this?  And how can I override it to get the old
behavior?

Increases the echo area and displays what, exactly?

I couldn't find anything relevant by looking for some keywords I could
think about.

Are you saying that something like the below

  (progn
    (message "One")
    (message "Two"))

when evaluated, displays

   One
   Two

in the echo area, instead of just "Two"?  Because it doesn't happen to
me with today's master branch: I see only "Two".  If the recipe to
reproduce what you see is something more complicated, can you please
post such a recipe?

It displayed both lines at once, one above the other, like this:

    Wrote /home/rms/outgoing/out-13
    Already 5

No, that displays only "Two".

I will see if I can make this fail again.

Were you able to reproduce this again?  I'm trying to determine if it
makes sense to keep this bug open.

More information was requested, but none was given within 4 months, so
I'm closing this bug for now.
