[PATCH v15 00/16] Interactive git clean

Update since v14:

 * Add more testcases for relative_path. See patch 01/16.

 * Refactor: change arguments name for relative_path (in path.c),
   i.e. abc -> in, base -> prefix. This is because the first
   argument is not restricted to absolute path any more.
   See patch 02/16.

 * Move git-ls-files fix from patch 05/16 to patch 03/16.
   See patch 03/16.

 * Remove NO_MINGW and related functions from t0060 script.
   See patch 16/16.
