Suggest most similar command when incorrect command is typed

[gbroques]

For example,

$ osewb lintt
osewb: error: argument command: invalid choice: 'lintt' (choose from 'test', 'lint', 'docs', 'make', 'browse', 'br', 'build', 'bld')

We could say: did you mean osewb lint?.

For example, git does this:

$ git checkoutt
git: 'checkoutt' is not a git command. See 'git --help'.

The most similar command is
        checkout
