That might be okay, but how does it help us get the Enchant support in
ispell.el DTRT?  We'd still need to detect when Ispell is used as the
back-end speller, no?

The issue here is that the current code already "patches" the nil case
to use [:alpha:] when Aspell or Hunspell are the spell-checker, and we
need to do that for Enchant.  If you are saying that Enchant doesn't
need to worry about the Ispell case, we could just modify
ispell-find-enchant-dictionaries to always "patch" the nil entry to
use [:alpha:], and leave the rest of the code, which already works,
intact.  If Enchant does need to cater to Ispell, we need a more
complex change, but again it's local th the Enchant support code.
