Hi Anthony,

In ASCII, `' are both left/right quotes and grave/acute accents.

Common practice historically, I was there for some of it, was to use `'
as left/right quotes, e.g. in ASCII text files intended to be
line-printed directly; no roff in sight.

They were drawn symmetrically nearly universally as anything else would
render the normal use incorrectly. DEC's VT 52 character ROM had, and
I've gone back to the ROM to check,

Their VT 220 was the same apart from more blank rows. The DEC VTs were
everywhere. A main competitor was Lear Siegler. I cut my teeth on
their lovely ADM-3A with its flip-top lid. It did the same as DEC and
the ASCII table in its manual showed `' as left and right quotes;
neither was straight. Wyse, Hazeltine, probably every manufacturer in
/etc/termcap rendered `' symmetrically.

That's incorrect, as my quoting parts to Ingo earlier today showed.

Hopefully, it will prompt them to be curious about the history and
learn. :-)
More important than `fixing' this IMO is having man pages that can be
input in an easy manner for simple things, e.g. `' in prose, and have
the output be good for the device used, i.e. ‘’.
