+Subject: [PATCH] Improve lexgrog(1) portability
+
+This fixes a test failure in man1/lexgrog.1 when building against groff
+1.23.0.
+
+Borrow code from groff 1.23.0's "an-ext.tmac" file (licensed as
+permissively as a decadent society) to implement `EX` and `EE` extension
+macros from Ninth Edition Research Unix (1986) (and groff) to get
+monospaced code displays in a more portable way.  There is no way to
+portably change font families in pure man(7) itself, and the names of
+troff typefaces aren't very portable either.  There is also no portable
+way to test for the _existence_ of a font.  FTW.
+
+("Portable" here largely means "to AT&T device-independent troff
+implementations", for which there has been no official source since the
+mid-1990s.[1]  Several AT&T Unix System V licensees/descendants have
+continued to ship their own vendored versions, but these have enjoyed
+little or no development for the past 3 decades.)
+
+* Define a string `mC` to store the name of a presumed monospaced roman
+  typeface.  Use "CW", which is portable to AT&T device-independent
+  troff of the early 1980s before it occurred to anyone that Courier
+  might someday be available in italic and bold styles (and budget
+  available to purchase them).
+* Define `mC` as "CR" if using a typesetting device and the formatter is
+  groff, or claims groff compatibility by the setting the `.g` register.
+  This is reasonably portable to modern implementations given
+  traditional troff font naming practices and the pervasive influence of
+  Adobe Software and the "base fonts" of its PostScript and PDF
+  specifications.
+* If not typesetting (i.e., if using nroff), define `mC` as "R", which
+  is certain to be available.
+* Define `EX` and `EE` macros as groff does, if the formatter does not
+  set the `.g` register.
+* Migrate from `ft CW` and `nf` requests to `EX` macro calls.
+* Migrate from `ft P` and `fi` requests to `EE` macro calls.
+* Replace an inline use of `\f(CW` with a change to inline bold.  There
+  is to date no portable way to inline a font family change.
+
+Test passes now.  Tested as-is and with the `EX` and `EE` macro
+definitions forcibly enabled.
