That feature is useful for text that you're editing.
But I don't think it is useful in a help string which is displayed
only for you to read. So I think it is good to suppress it for
help strings generally.
The only exception I can imagine would be if a doc string displays an
example of buffer or file contents containing a non-breaking space.
In principle, it would be good to make an exception for that case.
But I think that exceptional case would be difficult to detect
reliably. Also, since doc strings generally don't include examples of
buffer or file contents, I think that case will never actually occur.
So I think we can get away with ignoring it.
It is ever worth doing, we could create a kind of quoting to force a
real NBSP into the displayed help string.
