Rename and extend an existing testcase to cover more recently found mod_dav
encoding/escaping problems.

Most likely both mod_dav and mod_dav_svn need patches to resolve the test
failures here. Most of these (but not all) are regressions against earlier
Subversion/Httpd versions.

* subversion/tests/cmdline/basic_tests.py
  (windows_paths_in_repos): Rename to...
  (special_paths_in_repos): ... this and add several cases. Mark XFail for
    mod_dav.

  (test_list): Update reference.
