The `dirname` and `dirbase` methods have been replaced with the Android
implementation, which is actually compilant to some kind of standard.
A new method `topdir` has been added, which returns the topmost
directory in a path.
These changes fix issue #49:
`gitfo_prettify_dir_path` converts "./.git/" to ".git/", so
the code at src/repository.c:190 goes out of bounds when
trying to find the topmost directory.
The new `git__topdir` method handles this gracefully, and the
fixed `git__dirname` now returns the proper value for the
repository's working dir.
E.g.
/repo/.git/ ==> working dir '/repo/'
.git/ ==> working dir '.'
