git checkout new branch suggestion improvement

[JemarJones]

Currently if i do the following:

> git checkout my-new-branch
 error: pathspec 'my-new-branch' did not match any file(s) known to git.
> fuck

I get the following suggestion:

> git branch my-new-branch && git checkout my-new-branch

This works fine, but what i more likely meant (and this does the same thing) is:

> git checkout -b my-new-branch

This is much more succinct and should probably be the suggestion in my opinion.
