`redundant_field_names` with ranges

[ordovicia]

Playground

Clippy suggests replacing variable start with start and end with end used in range syntax.
I guess that is because the syntax is syntactic sugar and structs resulting from desugaring have fields with these names.
IMHO we should make an exception to treat these range syntax.

Hit this as well this morning, when my CI started to fail after update to 0.0.187.
