There are two kinds of change: one drops parentheses and one drops a
space.  Both are good, but they should be in two separate patches.

The second one is because Coccinelle implicitly ignores parentheses,
unless you tell it not to, so it actually matches and repretty prints all
returns.  In the second case it caused a change.
