help.autocorrect: do not run a command if the command given is junk
If a given command is not found, then help.c tries to guess which one the user could have meant. If help.autocorrect is 0 or unset, then a list of suggestions is given as long as the dissimilarity between the given command and the candidates is not excessively high. But if help.autocorrect was non-zero (i.e., a delay after which the command is run automatically), the latter restriction on dissimilarity was not obeyed. In my case, this happened: $ git ..daab02 WARNING: You called a Git command named '..daab02', which does not exist. Continuing under the assumption that you meant 'read-tree' in 4.0 seconds automatically... The patch reuses the similarity limit that is also applied when the list of suggested commands is printed.
