 The \fB\-w\fR option specifies the output width, padding and spacing
 of the formatted calendar output.  \fICol\fR specifies the number of
-columns in the output device.  If not specified, or specified as 0,
-it defaults to the larger of 71 or the actual width of your terminal,
-or to 80 if standard output is not a terminal.  If specified as the letter
-\fBt\fR, then \fBRemind\fR attempts to get the width of the
-\fB/dev/tty\fR terminal device.  This is useful, for example, if you
-pipe calendar output into \fBless\fR; even though standard output
-is a pipe, you want the calendar to be sized correctly for your
-terminal window:
