Bug description:substr() returns false for empty string
Description:
------------
substr() should not return FALSE if is used with empty string. Yes, it is
documented behaviour (If $string is less than or equal to $start characters
long, FALSE will be returned), but it is not expected behaviour. There is
no way to use "smaller $start".
Test script:
---------------
substr('x', 0, 2) // returns again 'x'
substr('', 0, 2) // returns FALSE but '' is expected
