Ordering in guc.c vs. config.sgml vs. postgresql.sample.conf

Hi,

While working on
http://www.postgresql.org/message-id/CABUevEzwMa9y+Bp4Fi4fE4hmPfZMjOZOmuLVtbHhPWtcujrmLg@mail.gmail.com
I once more taken aback by the total lack of consistency between the
three files in $subject. Some of the inconsistency of guc.c vs. the rest
comes from having separate lists for different datatypes - hard to avoid
- but even disregarding that, there seems to be little to no
consistency.

How about we try to order them the same? That's obviously not a 9.6
topic at this point, but it'd probably be good to that early in 9.7.
