The label() routine in /usr/lib/lib4014.a is badly broken in UNIX
System V Release 2.  The incremental plot mode offset makes very
little sense since it cannot restore the initial location before
the character is plotted, it makes even less sense when several
characters are in the label, and terminals such as the Tektronix
4105 do not understand the incremental plot codes.  To make matters
worse, the label() routines forgets to forget its current location
(oloy, ohix, ohiy, oextra should be reset to -1), so future vector
instructions may output incorrect short co"ordinate sequences.

Source for the broken module is something like
	/usr/src/lib/libplot/t4014/label.c .
Affected utilities include tplot (via /usr/lib/t4014) and lots of
stuff in PWB/Graphics.

Grrr.
