[PATCH 1/9] spec: process chars like other integer types

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

When parsing specifiers, Sparse process chars independently
of other integers. But this is not necessary (as long as the
proper see/test/set flags are correct).

Change this by processing chars the same as other integers
but 'below' shorts.
