Some popt improvements:
- Fixed a bug in short-opt parsing when an abutting arg has an '='. - Allow a short-opt to be separated from its arg by an '='. - Avoid an IBM-checker warning about an impossible case in a switch and a warning about a potential NULL-pointer dereference. - Fixed a memory leak.
