Incorrect docs in get_the_terms().

[mfields]

I've recently used get the terms outside the loop successfully, but the docs state that it must be used inside the loop both in the Codex an inline. I believe this to be an error. Please correct me if I am wrong.

[mfields]

Remove potentially incorrect documentation.

It's accurate only when the $id is not passed (or rather, is 0/false/null, since the next argument is required) and you're outside the loop. This change is fine to me.

[mfields]

Should docs be updated to reflect this? I'll upload another path if so.

These functions are odd in that $id has a default but is followed by a non-optional taxonomy. The default should likely be removed. I don't know that we should bother documenting passing 0. Might as well just past the ID since you have to pass something.

#15160 added a default. It seems we should do the opposite and remove these defaults since taxonomy is not optional.
