I am trying to pull from local repos using relative remote urls like ../my_other_repo. remote.download() fails with Unsupported URL protocol. The standard git cli doesn't do this, and seems to store relative paths as such in the config file. Converting to file:///absolute/path/to/my_other_repo seems to work. Can anyone confirm that I'm on the right track and, also, is there any way to know which transports are supported/required?
