 Short answer: `trim_copy` returns a new container of the same type
 containing a copy of the input (w/o leading and trailing spaces)

 Since `string_ref` doesn't actually own the underlying characters, it
 can't make a copy of them and return a `string_ref` to the copy. (where
 would it put the characters that it copied?)

 That being said, I could see how `trim` (not `trim_copy`) on a
 `string_ref` could be a desired features.

 Changing to a feature request.
