Spurious spellcheck results

This does not happen in all cases, but behavior is consistent when it does.

Here is a short description of the two, closely related problem cases:
1. Some correctly spelled words are returning as not spelled correctly, with the original, correctly spelled word with a single oddball character appended as multiple suggestions.

2. Some incorrectly spelled words are also returning multiple suggestions that are multiple copies of the same word with a single oddball character appended. Minus the oddball character this is a word that is a good correction for the original misspelling.

I will be attaching some more information to clarify the details.

The words involved are in the index, but without the spurious characters.
