I think you do not need the file-scope static levenshtein_cmd anymore with
this change, if you make similarity() take two command names.  No?

Please reroll the whole f66dd34 (git wrapper: DWIM mistyped commands,
2008-08-28), as it is not part of any solid integration branch yet.

You might also want to update the commit log message to talk about the
"len" reuse hack, but you already have in-code comment which might be
sufficient.
