[Groff] Rendering \(oq in ASCII and ISO 8859-1

[Colin Watson]

groff currently renders the single open quote character, \(oq, as `
(ASCII 0x60) in ASCII and Latin-1. According to
http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html, this is incorrect:

   Summary: Please do not use the ASCII grave accent (0x60) as a left
   quotation mark together with the ASCII apostrophe (0x27) as the
   corresponding right quotation mark. Your text will otherwise appear
   rather strange with most modern fonts (e.g., on Windows and Mac
   systems). Only old X Window System fonts and some old video terminals
   show ASCII 0x60/0x27 as left and right quotation marks, while most
   modern systems follow the ISO and Unicode standards instead. If you
   can use only ASCII's typewriter characters, then use the apostrophe
   character (0x27) as both the left and right quotation mark. If you can
   use Unicode characters, nice directional quotation marks are available
   in the form of characters U+2018 and U+2019.

Could \(oq in devascii and devlatin1 be changed to produce 0x27? I'll
supply a patch if wanted.

Thanks,
