Subject: [PATCH] check_file_directory_conflict path fix
Message-ID: <20050527025910.GA4836@localhost>

check_file_directory_conflict can give the wrong answers. This is
because the wrong length is passed to cache_name_pos. The length
passed should be the length of the whole path from the root, not
the length of each path subcomponent.

	$ git-init-db
	defaulting to local storage area
	$ mkdir path && touch path/file
	$ git-update-cache --add path/file
	$ rm path/file
	$ mkdir path/file && touch path/file/f
	$ git-update-cache --add path/file/f  <-- Conflict ignored
	$
