Old behavior was to take the first fuzzy match. Now, it checks the globa
git config, and runs the normal fuzzy handling, including failing to run a
semi-random command by default.
git-annex (but not git-annex-shell) supports the git help.autocorrect
configuration setting, doing fuzzy matching using the restricted
Damerau-Levenshtein edit distance, just as git does. This adds a build
dependency on the haskell edit-distance library.
