On some git hosting sites [*], if you copy the repository URL, you'll actually get "git clone some://url" in the cut buffer. When you then proceed to do "git clone <paste>" in the next terminal window, the command executed is actually this: $ git clone git clone some://url fatal: Too many arguments. As silly as the idea might sound, could the clone command possibly ignore these very specific extra arguments, and just proceed? This has happened countless times to me, and when I mentioned the idea on #debian-devel, there were others who had the same problem.
