The default is great (spelt '%s+'), but I'd object pretty violently to
'split by chars'.  I'd like to see 'split' cut a string into the exact
same pieces as 'gmatch', only to have split return exactly those
pieces that gmatch does not.  This semantics minizes the additional
cognitive load on the poor user :-)
