I think this is not TRT. 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. -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
