Description:
This command deletes the last segment (line or arc) of the current polygon.
\pldel may be used repeatedly, deleting the most recent segment of the
remaining part of the polygon. This command may only be used while working on
the current polygon (following commands such as \newp, \pcont). If you reply
`n' (no), you will be prompted to pick a new polygon point to draw to, until
you start a new command.
In order to close the polygon, (as in \endp), press <ENTER>.
