US 51-095 13.7.4p6.9 [temp.variadic] Add more bullets

[wg21bot]

In [temp.variadic], bullet (6.9) has two sentences

• In an attribute-list (9.13.1); the pattern is an attribute. In an annotation-list; the pattern is an annotation.

Proposed change:

Each sentence in 13.7.4/(6.9) should be its own bullet point, like this:

• In an attribute-list (9.13.1); the pattern is an attribute.
• In an annotation-list (9.13.1); the pattern is an annotation.
