The \fBinsdelln\fR and \fBwinsdelln\fR routines, for positive \fIn\fR, insert
\fIn\fR lines into the specified window above the current line. The \fIn\fR
bottom lines are lost. For negative \fIn\fR, delete \fIn\fR lines (starting
with the one under the cursor), and move the remaining lines up. The bottom
\fIn\fR lines are cleared. The current cursor position remains the same.
