What would be an example of situation-specific code formatting?
For me, that's when it makes sense to deviate from the default formatting, based on code context. For example, when you declare a function with ten arguments, and you'd normally put a new-line for every argument to leave place for descriptions and a better overview (yes, I am pro-short-line), but because you declare twenty alternative functions in the same place, you leave all arguments on one line.
It might sound strange at first, but in Rust it is quite common to do something like that:
define_open!{A}
define_open!{A, B}
define_open!{A, B, C}
define_open!{A, B, C, D}
define_open!{A, B, C, D, E}
define_open!{A, B, C, D, E, F}
define_open!{A, B, C, D, E, F, G}
define_open!{A, B, C, D, E, F, G, H}
define_open!{A, B, C, D, E, F, G, H, I}
define_open!{A, B, C, D, E, F, G, H, I, J}
define_open!{A, B, C, D, E, F, G, H, I, J, K}
define_open!{A, B, C, D, E, F, G, H, I, J, K, L}
define_open!{A, B, C, D, E, F, G, H, I, J, K, L, M}
define_open!{A, B, C, D, E, F, G, H, I, J, K, L, M, N}
define_open!{A, B, C, D, E, F, G, H, I, J, K, L, M, N, O}
define_open!{A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P}
define_open!(A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q);
define_open!(A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R);
