remove debugging remnant
Prevent infinite loop in ftf-find-locals-directory on Windows.

Root directories on Windows have a drive letter (e.g. "c:/"), so the
guard that detected the root directory (string-equal path "/") was
never true. Instead the root can be detected by checking to see if
(string-equal path (parent-dir path)).
Add hook section, including ff-find-related-file setup.
