I made such a change (on the master branch), not without some
trepidation, as the current behavior is very old (15 years), so I
wonder whether some feature relies on that.  We shall see, I guess.

Note that when nobreak-char-display is non-nil and non-t, we still
produce an ASCII space after the backslash-escape, so the display
engine will still wrap at that spot.  But here, I cannot make the same
change, because the Emacs manual clearly documents this behavior.

Thanks.
