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.

Dear maintainer,
the visual-line-mode minor mode wraps lines at non-breaking spaces
(U+000A0 No-Break Space, NBSP: ' '). It should not do that and instead
treat the sequence of characters before and after the NBSP as one
word. That is, if you have:
Lorem ipsum dolor sit amet
^
NBSP
Then visual-line-mode will consider the no-break space between 'dolor'
and 'sit' as a possible wrap point, which is contrary to what a no-break
space is meant to achieve.
To reproduce: enable visual-line-mode, write a document that contains a
NBSP, and shrink the window so that its edge hits the NBSP.
visual-line-mode will break the line at the NBSP, albeit it shouldn't.
