BF: allow for other section names which start with a string "remote"

by demanding a space after a word remote, and space is explicitly described as
a delimiter in man git-config:

To begin a subsection put its name in double quotes, separated by space from the section name,

otherwise e.g.

  File "/usr/lib/python2.7/dist-packages/datalad/support/gitrepo.py", line 836, in get_remote_branches
    for remote in self.repo.remotes:
  File "/home/yoh/deb/gits/python-git/git/repo/base.py", line 271, in remotes
    return Remote.list_items(self)
  File "/home/yoh/deb/gits/python-git/git/util.py", line 745, in list_items
    out_list.extend(cls.iter_items(repo, *args, **kwargs))
  File "/home/yoh/deb/gits/python-git/git/remote.py", line 453, in iter_items
    raise ValueError("Remote-Section has invalid format: %r" % section)
ValueError: Remote-Section has invalid format: u'remotes'
