Log:
MFC r298521;
regex: prevent two improbable signed integer overflows.
In matcher() we used an integer to index nsub of type size_t.
In print() we used an integer to index nstates of type sopno,
typedef'd long.
In both cases the indexes never take negative values.
Match the types to avoid any error.
