26   Return true if a trailing slash was removed.
27   This is useful when using file name completion from a shell that
28   adds a "/" after directory names (such as tcsh and bash), because
29   the Unix rename and rmdir system calls return an "Invalid argument" error
30   when given a file that ends in "/" (except for the root directory).  */
