Added, but I'll note that there are tons of locations in the docs where
we do not do that. Maybe they should all be made consistent.

It is capitalized because it refers to a section in the docs. I followed
it with <xref linkend="functions-info"> as well, so it ends up reading:
"There is a System Information Function (Section 9.25) called pg_config
which underlies this view."

I guess I could be convinced to lower case it, but I thought this looked
better.

The paragraphs are mostly copy-paste, but slightly different (toward the
end). There is both a function and a system view -- why would we not
want a description in both places?

Old habits die hard ;-)

No, intentional. The original version leaves a white space at the
beginning of CPPFLAGS after removing -DFRONTEND.

Right -- found and fixed several of these with Alvaro's help after
posting. Also fixed Copyright dates (s/2015/2016/) on the new files.

Fair enough -- fixed.

Thanks!
