5 Updates from /n/coma/usr/bwk/pic.
6 Brian picked up printlf() and I moved space() in openpl() in pixel and 4014,
7 	so no changes were needed in the source imported from bowell and bwk.
8 bwk's print.c calls arc(), which is translated in pl$DEV.c into a call to
9 	devarc() whose code is in lib$DEV/arc.c.
10 I didn't understand howard's dotline change and it conflicted
11 	with using pure bwk code, so I commented it out in pltex.c.

14 Updates from /n/bowell/usr/src/cmd/pic
15 Some changes in linegen.c (bigger buffers), misc.c, picl.l, picy.y, symtab.c
16 I removed the \t-><tab> transformation in picl.l (bwk agreed it was bogus).
17 Put the dotline change back in (to get smaller output files, and avoid
18 	problems where lines were bunching together).

21 Went back to troff dotline (the postscript one doesn't act the same
22 	as troff when scale!=1).
23 Changed default pen size from 8 to 9 (to give same thickness lines
24 	as default pic), and made dots change size with pen size.
