teach ei_x_format to handle unary - and +
Teach the format string parser used for ei_x_format() and
ei_x_format_wo_ver() about unary negative and positive operators on
numbers. Previously, passing a negative numeric constant or a positive
numeric constant with an explicit leading plus sign within the format
string would cause these functions to fail.
Augment the format_wo_ver unit test in the ei_format suite with a
regression test for these cases.
An easy way to reproduce the problem is to use erl_call:
erl_call -s foo@bar -a 'erlang list_to_integer [-1]'
Without this change, erl_call fails with a -1 exit status. With this
change, it properly prints "-1".
