hash.c: +(-1) is a wrong idea
Before this changeset RHASH_ARRAY_SIZE_DEC() was expaneded to include
an expression like `RHASH_ARRAY_SIZE+(-1)`. RHASH_ARRAY_SIZE is by
definition unsigned int. -1 is signed, of course. Adding a signed
and an unsigned value requires the "usual arithmetic conversions" (cf:
ISO/IEC 9899:1990 section 6.2.1.5). -1 is converted to 0xFFFF by that.
This patch prevents that conversion.
