Improve ispell dictionary's defenses against bad affix files.
Don't crash if an ispell dictionary definition contains flags but not
any compound affixes. (This isn't a security issue since only superusers
can install affix files, but still it's a bad thing.)
Also, be more careful about detecting whether an affix-file FLAG command
is old-format (ispell) or new-format (myspell/hunspell). And change the
error message about mixed old-format and new-format commands into something
intelligible.
Per bug #11770 from Emre Hasegeli. Back-patch to all supported branches.
