/* This file contains the endpath() method, which is a GNU extension to
libplot. A polyline object may be constructed incrementally, by
repeated invocation of the cont() routine. (See the comments in
g_cont.c.) The construction may be terminated, and the polyline object
finalized, by an explict invocation of endpath().
If endpath() is invoked when no polyline is under construction, it has
no effect. */
