copy-path-rec: bug: trailing slash fail.
* stdlib/copy-file.tl (copy-path-rec): When from-path has
a trailing slash, the starts-with test fails, and the operation
fails without doing anything. Let's just get rid of that test.
It's probably only there because of the ad-hoc path munging
that is calculating rel-path. Why don't we just use the rel-path
function for that.
