Contents of module with different name gets overwritten on other platform

[JoNil]

I have a file with

#[cfg_attr(target_vendor = "nintendo64", path = "graphics.rs")]
#[cfg_attr(not(target_vendor = "nintendo64"), path = "graphics_emu.rs")]
pub mod graphics;

So when i run cargo fmt the contents of the file graphics_emu.rs is written to the file graphics.rs.

I would expect them both to be formatted and kept in their separate files.
