US 216-357 33.9.2p49 [exec.snd.expos] Fix specification wording details

[wg21bot]

This paragraph should say "function template" instead of "function"; should say "new object of type remove_cvref_t<T>" instead of "new object of type T". Missing closing parens for the "i.e." after "is valid".

Proposed change:

Modify accordingly.

Except for the remove_cvref_t part, this is editorial.

[jensmaurer]

The existing specification already says that we're returning an object of type P, which is cvref-removed. So, this is all editorial.

[jensmaurer]

Accepted.
