Non-empty standard error or non-zero 31## exit code cause cancellation of the print request. 32## 33## Calling sequence: 34## 35## slow.filter prefix file1 file2 ... fileN 36## 37## "prefix" is prefix of full path name for output files. All we 38## do is append a ``-k'' for k = 1, 2, ..., N. 39########## 40 41##### 42# 43# Most of the time we don't want the standard error to be captured 44# by the Spooler, mainly to avoid "Terminated" messages that the 45# shell puts out when we get a SIGTERM.
