[PATCH v14 00/16] Interactive git-clean

Johannes found that some relative_path tests should be skipped on Windows.
See this thread:

  http://thread.gmane.org/gmane.comp.version-control.git/227706

In this reroll,

 * I squash Johannes's patch into patch 01/16, and seven relative_path
   test cases are skipped by marking with POSIX.
 
 * In patch 02/16, 4 test cases can run correctly as the refactor of
   relative_path.
 
 * In patch 16/16, most of the previous skiped test cases can run with
   the help of the new utiliy "test-path-utils mingw_path /abs/path/".
