Implement command forgiveness with autocorrect

Similar to `git`, when a user types an unknown command like `repo tart`,
we now use `difflib.get_close_matches` to suggest similar commands.

If `help.autocorrect` is set in the git config, it will optionally
prompt the user to automatically run the assumed command, or wait
for a configured delay before executing it.

Verification Steps:
1. Created a dummy repo project locally.
2. Verified `help.autocorrect=0|false|off|no|show` suggests
   command and exits.
3. Verified `help.autocorrect=1|true|on|yes|immediate`
   automatically runs suggestion.
4. Verified `help.autocorrect=<number>` runs after
   `<number>*0.1` seconds.
5. Verified `help.autocorrect=never` exits immediately without
   suggestions.
6. Verified `help.autocorrect=prompt` asks user to accept [y/n]
   and handles correctly.

repo

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

Contact

Please use the repo-discuss mailing list or issue tracker for questions.

You can file a new bug report under the “repo” component.

Please do not e-mail individual developers for support. They do not have the bandwidth for it, and often times questions have already been asked on repo-discuss or bugs posted to the issue tracker. So please search those sites first.

Install

Many distros include repo, so you might be able to install from there.

# Debian/Ubuntu.
$ sudo apt-get install repo

# Gentoo.
$ sudo emerge dev-vcs/repo

You can install it manually as well as it's a single script.

$ mkdir -p ~/.bin
$ PATH="${HOME}/.bin:${PATH}"
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
$ chmod a+rx ~/.bin/repo
