[PATCH v3 4/4] subtree: adjust function definitions to match CodingGuidelines

[David Aguilar <davvid@gmail.com>]

We prefer a space between the function name and the parentheses, and no
space inside the parentheses.

The opening "{" should also be on the same line.

This says "v3" but this is actually a branch new patch that wasn't included
in the previous iteration... calling it v3 since it's split out from the
previous patch.

They can be squashed together if desired, but this makes it a little
easier to review separately.
