Concision is good, straining for brevity or bad
formatting isn't.

I've seen a lot of ugly patches lately to "fix"
code like this by making it worse.

By default, there is still a long_line warning for
this style.  It arguably could be appropriate to
keep some lines like this and this makes it easy
to tell people "add --ignore=<type>".

This patch shouldn't be applied right now anyway.

I think the idea is OK, but this implementation
could be improved and clarified by moving the
current exclusions before the classifications.

Anyone else have an opinion?

I'll send a V2 later unless there are more comments.
