builtins (e.g., exit, strcmp).

0ab2a7ae85 Back out part of previous commit.
Arguments with whitespaces are easy to fix, but in combination with
shell metachars that should not be evaluated it is very hard, probably
impossible to fix without going to a line-oriented solution.

Next time I will believe Henry Spencer when he says "this looks easy
to fix but isn't".

18b3ba267c 1) Fix the case where a shellscript using getopt is called with a
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.

1c8af87873 compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.
