.SH DESCRIPTION
The \fBtouchwin\fR and \fBtouchline\fR routines throw away all
optimization information about which parts of the window have been
-touched, by pretending that the entire window has been drawn on. This
+touched, by pretending that the entire window has been drawn on.
+This
is sometimes necessary when using overlapping windows, since a change
to one window affects the other window, but the records of which lines
-have been changed in the other window do not reflect the change. The
+have been changed in the other window do not reflect the change.
+The
routine \fBtouchline\fR only pretends that \fIcount\fR lines have been
changed, beginning with line \fIstart\fR.
