[PATCH] lib: Improve _parse_integer_fixup_radix base 16 detection

[Michal Simek]

Base autodetection is failing for this case:
if test 257 -gt 3ae; then echo first; else echo second; fi

It is because base for 3ae is recognized by _parse_integer_fixup_radix() as
10. The patch is checking all chars to make sure that they are not 'a' or
up. If they are base needs to be in hex.
