inotify: fix issue1375, add a test. The biggest problem was the data structure, which did not allow changing a file into a directory or vice versa. This problem is fixed by b55d44719b47. The walk() method also had an issue in this case: - we know 'path' as a directory. inotify server sleeps. - 'path' is deleted - 'path' is recreated as a file - the server catches up here, and see the deletion. it instantiates a scan(), which in its turn calls for walk(repo, path). - walk() then assumes that 'path' is a directory and calls os.listdir on it, which raises an OSError(errno.ENOTDIR) Catch the error, and yield the file instead of the directory contents.
