parameter that has space in it, both in getopt.c and in the manpage
example.
2) Fix the example in the manpage. The set(1) command is required to
return 0 (POSIX 1003.2, section 3.14.11), so you can't test for
getopt's exit status like the example did:
#! /bin/sh
set -- `getopt abo: $*`
if test $? != 0 # wrong, tests for set's exit status, which is
# always zero, no for getopt(1)'s.
Fixes PR bin/5845, which thought it was getopt's fault, but in fact
the manpage was wrong.
I also updated the example to be more useful and updated the BUGS
section.
