odd bug in run-tests.php

Hi all, I don't have time to fix this now, but FYI, run-tests.php has very odd behavior if you don't put a space between a switch and its argument, and should error out. i.e. php run-tests.php -n -dextension_dir=blah -dextension=blah.so will ignore every other line. This: php run-tests.php -n -d extension_dir=blah -d extension=blah.so works as expected. I wasted about 4 hours rebuilding PHP yesterday (thinking this was the problem) because of this bug, so it would be a good one to kill for future poor people who are stupid like me. Thanks, Greg
