  Windows has some very strange rules for paths, and I remember fixing a subrepo bug with a path in the form `C:foo`.  I tried these, and can't think of anything more we'd need to worry about.
  
    >>> import os
    >>> os.path.isabs("/")
    True
    >>> os.path.isabs("C:/")
    True
    >>> os.path.isabs("C:tests")
    False
  
  (The last one being at the root of the hg repo.)
