As reported by Peter Krefting:
If git cannot start one of the external commands (at least some of them),
the DWIM engine is a bit flaky:
$ git citool
/usr/local/libexec/git-core/git-citool: line 10: exec: wish: not found
git: 'citool' is not a git-command. See 'git --help'.
Did you mean this?
citool
Now we check whether the best bet found by levenshtein() differs from
the command line or not before proceeding.
The new error is:
$ git citool
/usr/local/libexec/git-core/git-citool: line 10: exec: wish: not found
fatal: Failed to run command 'citool': No such file or directory

Is the call to strerror() useless anyway?
