style.9 RFC: Permit eliding blank lines in small functions

[Conrad Meyer]

Hi,

I have proposed a small change to style.9 here:

https://reviews.freebsd.org/D20448

I believe this has been generally permitted in practice and the change
is mostly to codify existing unwritten standards, rather than to
change them.  The goal of this thread is to determine if we do have
general consensus for the concept.

Thanks,
Conrad

P.S., please try to avoid the obvious bikeshed trap about the number 4.
