Lprm didn't work correctly, when we got our distribution for the VAX.

Index:	usr.lib/lprm 4.2BSD

Description:
	You would get after:
	   $ print /etc/passwd
	   $ lpq
	   lp is ready & printing
	   Rank	Owner	Job   Files			Total Size
	   active  jaap	219	/etc/passwd		5790 bytes
	   $ lprm jaap
	   dfa219mcvax dequeued
	   cfa219mcvax dequeued
	   /usr/lib/lpd: mcvax: unknown printer
	   lprm: lp: cannot restart printer daemon
	(Assumed is that the log file is /dev/console, and you are doing
	this on the console...)

Caused by:
	rmjob tries to restart the daemon with startdaemon(host),
	instead of startdaemon(printer).
Fixed by:
	change the call startdeamon(host) into startdeamon(printer) in rmjob.c

Since we are talking about the spooler things, here is another one:

Index:	usr.bin/lpr/vplotf.c

Description:
	The vplotf filter produces a square instaed of a circle
Fixed by:
	The definition of labs(a) needs some more brackets, else an if statement
	will do something, what it is clearly not supposed to be in the routine
	circle().
	So this is the right define:

#define labs(a) ((a) >= 0 ? (a) : -(a))

By the way, has anybody an just as elegant algorithm for generating an arc
as the one for a circle?
