Support same name repository

[Sixeight]

Support same name repository like Bundler. (see also: http://bundler.io/v1.6/git.html)
We can ghq get ruby then clone https://github.com/ruby/ruby now.

(I'm sorry for new last line...)

Do I support /ruby ?

gofmt please? (and then the last blank line should be removed)

[motemen]

I don't think we should support paths starting with "/" (e.g. "/ruby" expands to "https://github.com/ruby/ruby). You can fail with error or leave the behavior undefined in that case.

[Sixeight]

Oh, I'm sorry. fix it soon.

[Sixeight]

@motemen Fixed. Please review again.

Thank you for your mention of paths starting with "/". I decided to avoid "/ruby" case. Current behavior /ruby => https://github.com/ruby, /ruby/ruby => https://github.com/ruby/ruby.

[motemen]

debugging line remained?

[Sixeight]

I'm very very sorry..
