file's multiple includes on 1 line

[2bndy5]

when creating the solution for #757, I noticed that the includes list of files would only span 1 line despite having multiple included files.

example from breathe docs:

I found an easy fix for this:
https://github.com/michaeljones/breathe/blob/aec47028e05ad8d77e960db9d25140e9fd1c0127/breathe/renderer/sphinxrenderer.py#L1700-L1706
Should return

        return [nodes.container("", nodes.emphasis(text=text))]

which puts each emphasized text into a separate div element.

swing and a hit

I tried my hand at making the local include files cross-referenced links... I managed this using visit_docreftext(), but I had to add an empty list as a class attribute (named para) to incType in compoundsuper.py

Stay tuned for another PR.
