> The copy commands currently do not provide a way to disambiguate the expected destination
of a copy.  Ex.
> {{fs -put myfile path/mydir}}
> If "mydir" is an existing directory, then the copy produces {{path/mydir/file}}.  If
"mydir" does not exist at all, the copy produces {{path/mydir}}.  The file has unexpectedly
been renamed to what was expected to be a directory!  It's standard unix shell behavior, but
it lacks a special trait.
> Unix allows a user to disambiguate their intent by allowing {{path/mydir/}} or {{path/mydir/.}}
to mean "mydir" is *always* be treated as a directory.  If the copy succeeds, it will always
be called {{path/mydir/myfile}}.
