 \*(C` and \*(C' are quotes in nroff, nothing in troff, for use with C<>.

 Escape single quotes in literal strings from groff's Unicode transform.

 If the F register is >0, we'll generate index entries on stderr for
 titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
 entries marked with X<> in POD. Of course, you'll have to process the
 output yourself in some meaningful fashion.

 Avoid warning from groff about undefined register 'F'.
