[Message part 1 (text/plain, inline)]

I found a bug recently where, when using Enchant as the back-end for
ispell.el, spellchecking was locking up for some languages.

This turned out to be the combination of two problems.

First, ispell-find-enchant-dictionaries was incorrectly merging
ispell-dictionary-base-alist into its result. This caused the
ispell-set-spellchecker-params to fail to add the correct "-d LANG" flag
arguments to the list of dictionaries that it used to start Enchant, which
in turn meant that the process was started as e.g.

enchant-2 -d francais # rather than -d fr_FR

and failed to start properly. I have fixed this by simply removing the
incorrect code (patch 0003 attached).

Secondly, ispell.el failed to notice that it had not actually started an
Enchant process, and hung while trying to read from it in
ispell-accept-output. I fixed this by testing that the process is live
before trying to read from or write to it (patch 0002 attached).

Finally, while reading the source code I found an ancient comment that is
more of a commit message in spirit (it explains how the current code came
to be that way, rather than explaining something about how it works), so I
removed it (patch 0001 attached).

As usual with my infrequent patches, I would appreciate other eyes on them
before I install them, if possible. I remain an active user of ispell with
Enchant, though, so I will give them plenty of manual testing. Thanks in
advance!
