Repositories with extension-like suffixes (e.g repo.foo) are not properly handled

[Pierre-Etienne Poirot]

Example:

$ git clone git://tournevis.dyn.syd.atlassian.com/PROJECT_1/test-123_DEF.foo
Cloning into 'test-123_DEF.foo'...
fatal: remote error: Invalid repository name '/PROJECT_1/test-123_DEF.foo'.
