-Subject: [PATCH] Store formatted variables in a variable
-
-This fixes compilation errors when compiling with slightly less recent
-rust compilers, e.g. 1.78.0 and 1.77.1.
-
-The performance overhead of formatting the string here is neglegible in
-any case since the string is only discarded if there are zero or one
-variables, in which case the extra call to `join` is very cheap.
