   **  \fT%?<sequence_char>?<optional_string>?\fP

   ** where \fIsequence_char\fP is a character from the table above, and

   ** other sequences as well as normal text, but you may \fBnot\fP nest
   ** optional strings.

   ** Here is an example illustrating how to optionally print the number of
   ** new messages in a mailbox:
   ** .pp
   **  \fT%?n?%n new messages.?\fP
   ** .pp
   ** Additionally you can switch between two strings, the first one, if a
   ** value is zero, the second one, if the value is nonzero, by using the
   ** following construct:
   ** .pp
   **  \fT%?<sequence_char>?<if_string>&<else_string>?\fP
   ** .pp
   ** You can additionally force the result of any \fTprintf(3)\fP-like sequence

   ** (\fT_\fP) sign.  For example, if you want to display the local hostname in
