Expected behavior

According to cs_v6_release_guide, I just set cs_option(handle, CS_OPT_DETAIL, CS_OPT_DETAIL_REAL);, and I found the details is part invalid.

Changing code to cs_option(handle, CS_OPT_DETAIL, (CS_OPT_ON | CS_OPT_DETAIL_REAL));, it works.

I think it's better to make CS_OPT_DETAIL_REAL implicitly turn on the detials? or maybe the doc need to update, and don't generate groups and condition info and condition when detail turned off.

Actual behavior

console print ERROR: Too many groups defined in instruction mapping.
and groups info pile up while no other details.
