bug#21472: 25.0.50; REGRESSION: (emacs) `Coding Systems' uses curly quotes for Lisp strings

[Drew Adams <drew.adams@oracle.com>]

Emacs Info manuals have long used double-quotes for two things:

* Setting off terms that are defined (e.g., glossary terms).
  (This is presumably the case for the occurrence of "codepages"
  in this same node.)

* Programming strings - e.g. Lisp strings (including file-name strings).

In (emacs) `Coding Sytems', at least, it seems that Curly-Quote Mania
has struck another nasty blow:

   In addition to converting various representations of non-ASCII
 characters, a coding system can perform end-of-line conversion.  Emacs
 handles three different conventions for how to separate lines in a file:
 newline ("unix"), carriage-return linefeed ("dos"), and just
 carriage-return ("mac").

Why curly double-quotes here?  Either those quoted names are supposed
to be Lisp strings or they are proper names.  In the latter case they
should not be quoted at all, and they should be properly capitalized.
In the former case (which is what I'm guessing is meant), plain ASCII
double-quote chars should be used.

Please don't confuse users this way, and make them guess what is meant.
Get it straight, please.

Plain ASCII double-quote chars should always be used for strings.
