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). */
