Note that the .SH DESCRIPTION line contains \F rather than \f for the
font commands. (That is, \f has gotten capitalized along with the rest of
the section header text.)  I suppose this might be insignificant, given that
.SH generates boldface anyway. Older manpage stylesheets appear to strip the
font commands, which at least doesn't result in warnings when the manpage
is formatted:

% groff -man some-program.1 >/dev/null
some-program.1:15: warning: can't find font `BB'
some-program.1:15: warning: can't find font `RB'
