Documentation/CodingStyle: flesh out if-else examples
There is a missing case for "Chapter 3: Placing Braces and Spaces". We often know we should not use braces where a single statement. The first case is: if (condition) action(); Another case is: if (condition) do_this(); else do_that(); However, I can not find a description of the second case.

This does not apply if one branch of a conditional statement is a single
statement. Use braces in both branches.
