set-option completion shown after first argument is set

[askreet]

Summary

Noticed this while looking at #5939. If you start typing :set-option bufferline you get completion while typing bufferline. If you then press space you get new completion of options for the 2nd argument. Perhaps we want completion that is related to the option, but at least the completion probably should not be displayed for the 2nd argument.

Reproduction Steps

I tried this:

1. Start typing set-option mouse true.

I expected this to happen:

No completion after set-option mouse while typing the 2nd argument.

Instead, this happened:

New completion showing all options is shown.
