erlang:binary_to_integer/1 and /2 fail to detect invalid input consisting of a single + or - sign but nothing else. For an input like <<"+">> they return 0, while list_to_integer/1 correctly signals a badarg for "+". Fixed by checking if the input is empty after the initial +/- sign processing. Added a test case which fails without this fix but passes with it. Thanks to "niku" for reporting the issue.
