  ** .pp
  ** where \fIsequence_char\fP is a character from the table above, and
  ** \fIoptional_string\fP is the string you would like printed if
  ** \fIsequence_char\fP is nonzero.  \fIoptional_string\fP \fBmay\fP contain
  ** other sequences as well as normal text, but you may \fBnot\fP nest
  ** optional strings.
  ** .pp
  ** Here is an example illustrating how to optionally print the number of
  ** new messages in a mailbox:
  ** .pp
  ** \fC%?n?%n new messages.?\fP
  ** .pp
  ** You can also switch between two strings using the following construct:
  ** .pp
  ** \fC%?<sequence_char>?<if_string>&<else_string>?\fP
  ** .pp
  ** If the value of \fIsequence_char\fP is non-zero, \fIif_string\fP will
  ** be expanded, otherwise \fIelse_string\fP will be expanded.
  ** .pp
  ** You can force the result of any \fCprintf(3)\fP-like sequence to be lowercase
  ** by prefixing the sequence character with an underscore (``_'') sign.
  ** For example, if you want to display the local hostname in lowercase,
  ** you would use: ``\fC%_h\fP''.
