lprng & ps-to-printer.fpi

[Emiel Metselaar <e.d.metselaar@phys.rug.nl>]

I was trying to print using lprng on a woody machine and it did not work.
After some poking around i found that in 
/usr/share/lprngtool/ps-to-printer.fpi something did not work allright.

It seems that the line "source ${SPOOLDIR}/postscript.cfg" does not
work. I am not much of a shell script expert, but that works under bash.
So changing the first line from:
"#!/bin/sh"
to
"#!/bin/bash"
Gives a workable sollution. My questions are now, is this regarded as a bug , 
is it known and how does the sourcing in a sh script work?
