A friend who uses Mercurial pointed this out as a reson why Git is evil:
rasky@lilax:~/src$ git clone git://www.develer.com/doesnt-exist Initialized empty Git repository in /home/rasky/src/doesnt-exist/.git/ fatal: The remote end hung up unexpectedly
Plus, the directory was not really there :-)
rasky@lilax:~/src$ hg clone hg://www.develer.com/doesnt-exist abort: repository hg://www.develer.com/doesnt-exist not found!
rasky@lilax:~/src$ svn co svn://www.develer.com/doesnt-exist svn: URL 'svn://www.develer.com/doesnt-exist' doesn't exist
