I think the question was clear enough: remove the trailing
slashes, but turn "////" into "/" instead of "" as ${VAR%%+(/)}
would (though as Eric pointed out, one may want *not* to turn
"//" into "/" as "//" and "/" are different paths on some

Now, one may want to do more clean-ups in paths like remove
consecutive slashes within (foo//bar), or remove redundant "."
components (foo/./bar, /foo/., ...).
