Just for precision's sake, the .g register interpolating a true value means (by convention) that an implementation is claiming support for groff extensions. This happens with Heirloom Doctools troff, for instance, if one gives it the "-mg" option. (There are other ways to switch on its "groff mode".) Also, to reiterate, "CW" as a font name is not a groff extension; it has some history in Documenter's Workbench troff and I think it may have appeared in Research Unix troff as well in the 1980s, but I don't have convincing evidence of this, just educated guesses based on man(7) and ms(7) man pages from that era. If I had sources for Research Unix V8-V10 I'd be a happy guy. > I toyed with using \f[CW] instead of \f(CW to underscore that it's > groff-specific. However, that might be overkill given the number of > non-*roff programs that read these files. In my opinion that's not necessary, and implies too much.
