   8 # Remove optional braces of control statements (if, else, for, and while)
   9 # according to the LLVM coding style. This avoids braces on simple
  10 # single-statement bodies of statements but keeps braces if one side of
  11 # if/else if/.../else cascade has multi-statement body.
  12 #
  13 # As this rule comes with a warning [1], we want to experiment with it
  14 # before adding it in-tree. since the CI job for the style check is allowed
  15 # to fail, appending the rule here allows us to validate its efficacy.
  16 # While also ensuring that end-users are not affected directly.
