4.2BSD lpd indentation bug

[Chuck Privitera]

As noted by fluke!jeff:

> Index:	usr.lib/lpd/printjob.c 4.2BSD
> 
> Description:
> 	If a job is queued to a printer with a request that it be indented,
> 	subsequent printouts within the same queue run will be given the
> 	same indentation.
> 
> 	The problem exists because the instantiation of /usr/lib/lpd which
> 	processes the queue doesn't reset all its variables after printing
> 	each job.  Specifically, it doesn't reset the indent amount to zero.
We fixed this one a long time ago. Forgot to post it to the net
though. Sorry. Lpd doesn't reset the page width passed on to pr(1)
either.  So in addition to Jeff's fix:
> Fix:
> 	In the file usr.lib/lpd/printjob.c, find the function printit().
> 	Add the one new line shown below in context.

Add this line:

	sprintf(width, "-w%d", PW);	/* page width in characters */
