Description:
------------
createFromFormat fails when in the format D or l is followed by separators that 
are not space or comma. 

Test script:
---------------
$string = "Thu., Nov. 29, 2012 5:00PM";

$data = DateTime::createFromFormat( "D., M# j, Y g:iA", $string );

var_dump( $data );
var_dump( DateTime::getLastErrors() );

Expected result:
----------------
object(DateTime)#1 (3) {
  ["date"]=>
  string(19) "2012-11-29 17:00:00"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(19) "America/Los_Angeles"
}
array(4) {
  ["warning_count"]=>
  int(0)
  ["warnings"]=>
  array(0) {
  }
  ["error_count"]=>
  int(0)
  ["errors"]=>
  array(0) {
  }
}


Actual result:
--------------
bool(false)
array(4) {
  ["warning_count"]=>
  int(0)
  ["warnings"]=>
  array(0) {
  }
  ["error_count"]=>
  int(2)
  ["errors"]=>
  array(2) {
    [0]=>
    string(32) "A textual day could not be found"
    [4]=>
    string(40) "The separation symbol could not be found"
  }
}
