Subject: [PATCH] Change rustdoc style so fully qualified names do not overlap
 src links

A type's fully qualified name will now wrap once it gets to the
`[-][src]` link aligned against the right edge of the content area.
Previously the two would overlap and the name would only wrap when
hitting the edge of the content area. The `[-][src]` link will main at
the top of the header.
