There is a fallback to regex if expression isn't supported by regis (see call
of RS_isRegis() in spell.c).
Regis supports only matches as is, range of characters ( [abc] ), negotiation of
characters range ( [^abc] ) and can match begin or end of string. AFAIK, ispell
allows full regex but in practice I never seen something unsupported by regis.
