Subject: 0005 Do not reorder words
ispell reorders words in personal dictionary without good reason.
The correct approach is to build the internal data structure with variant
spellings stored in the same order as they appear in the personal dictionary.
Fortunately, this is easy, though the patch is to a different file. This one
has been tested (That's what I get for trying to rush out a fix before a
meeting!).
