 /* Remove trailing slashes from PATH.
+   Return nonzero if a trailing slash was removed.
    This is useful when using filename completion from a shell that
    adds a "/" after directory names (such as tcsh and bash), because
    the Unix rename and rmdir system calls return an "Invalid argument" error
    when given a path that ends in "/" (except for the root directory).  */
