Hello Felicián,

I pushed an alternate version of this patch to the branch
scratch/eldoc-display-functions

To git.sv.gnu.org:/srv/git/emacs.git
 * [new branch]            scratch/eldoc-display-functions -> 
scratch/eldoc-display-functions

It contains more than just this patch, but notably it passes your test,
I think.  Can you try it out?  A point of mention is that the value `t'
is now what `aggressive' used to be.  This is more straightfoward and
much simplified  docstring writing the docstring.  If you want the old
"only prefer if truncated" behaviour, set it to `maybe' (maybe that name
can be reviewed).

Best regards,
João
