    gbfont f
        Set the bold font to f.

    gfont f
    gifont f
        Set the italic font to f.  gifont is a GNU extension.

    grfont f
        Set the roman font to f.

I think ‘is a GNU extension’ is typical language for GNU documentation.

The user should see a message which uses the keyword they entered.
It's annoying to search for ‘gifont’ and not find it, as will be typical.

One way to do this would be to have GFONT and GIFONT and only treat them
the same later on.
