2 letter short options don't work as documented

I added the following to the the demo.php file.

opt->add( 'za|zooa?' , 'option with optional value. za' );

You can retrieve the value if I use the long option:

php demo.php -f 1 -z 1 --zooa 1

If you try and retrieve the value using the short form you get "Invalid option -a"

php demo.php -f 1 -z 1 -za 1

The option like -abc which is a combined options from:

opt->add( 'a|foo' , 'option with optional value. a' );
opt->add( 'b|bar' , 'option with optional value. b' );
opt->add( 'c|bar' , 'option with optional value. c' );

which is just like we use the grep options today:

  grep -irl [pattern] [file]

Oh! there's the confusion. Sorry about that.
