Loading fonts in ditroff

[eric%UCBARPA%berkeley at sri-unix.UUCP]

-me uses the numeric values for fonts internally because otherwise
you cannot load other fonts.  For example, if it were to use B for
bold font, it would only work if you had Times Roman loaded -- if
you wanted to use Hershey, the font change macros would die.  I
agree that this is a botch, but it seemed that the alternative was
worse.
