Description:
------------
Depending on the order that command line options are passed, it is possible to 'bypass' a required value for a short option which erroneously assigns another option as the value to the previous option.

Test script:
---------------
<?php
// filename test.php
require_once 'Console/Getopt.php';
$options = new Console_Getopt();
$ret = $options->getopt($options->readPHPArgv(), 'i:r::l', array('file=','test=='));
if(PEAR::isError($ret))
{
die($ret->getMessage()."\n");
}
else
{
var_dump($ret);
}
?>

Correct results
$ php test.php -l -i

Incorrect results
$ php test.php -i -l

Expected result:
----------------
$ php test.php -l -i # Behaves correctly

$ php test.php -i -l
Console_Getopt: option requires an argument -- i

Because -i is missing its value and -l is a different option.

Actual result:
--------------
# Incorrect behavior
$ php test.php -i -l
array(2) {
[0]=>
array(1) {
[0]=>
array(2) {
[0]=>
string(1) "i"
[1]=>
string(2) "-l"
}
}
[1]=>
array(0) {
}
}

# Correct behavior
$ php test.php -l -i
Console_Getopt: option requires an argument -- i
