Return true if a trailing slash was removed.

This is useful when using file name 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 file that ends in "/" (except for the root directory). */
