Emacs should cater to user expectations before it caters to
abstractions, IMO.  It is good to use abstractions, but if an
abstraction cannot support some useful feature, it should take a back
seat, and we should implement the feature based on lower-level
infrastructure.

In this case, using enchant-lsmod to figure out the engine, and then
using the existing code in ispell.el that supports that engine is an
okay solution when Enchant itself cannot provide the information we
need.

Of course, if/when Enchant provides the means to get at the
information we need, we should switch to using those means.
