* Eager-load comment user data
Profiles and user settings are loaded for on each comment author. On
posts with many comments, this invokes a *lot* of DB queries. This
commit replaces 2 queries per comment with 2 queries for all comments.
* Fix where I misunderstood limit's purpose
This implementation is too clever. It looks like it should just be
getting all but the last, but it uses the fact that the default is 0 to
default to getting all of them. This isn't readily understandable to
someone reading the code.
I don't have a suggestion to fix it yet so I'm just going to leave it
as-is for now.
