[cfe-dev] Getting around LibFormat

[Jessica Hamilton via cfe-dev]

And if I want to format a particular block of code conditionally, how
would I go about that?

E.g. we have different variable alignment rules for class definitions
compared to function definitions. In a class, member variable names
are aligned, but in functions, there is no variable name alignment.
