Right.

See FLG_EXTERNAL_SET and do things similarly. Note that
FLG_EXTERNAL_SET uses FLG_CRACKING_SUP, whereas e.g. FLG_INC_SET uses
FLG_CRACKING_SET. I think you should similarly use FLG_CRACKING_SUP in
FLG_MASK_SET.

This depends on how you implement the wordlist + mask mode combination -
which of the two modes is the primary and which is added on top of it or
invoked by it.
