Subject: [PATCH] Three bugfixes in mkdir(1)

1) Any path passed to mkdir -p beginning with '/' failed, because
   it would cut out the first '/' immediately, passing "" to mkdir.
2) Running mkdir -p with a path/to/dir without trailing '/' would
   not create the directory.
   This is due to a wrong flag-check I added in the main-loop.
   It should now work as expected.
3) With the p-flag given, don't report an error in case the last
   dir also exists.
