When using `quote` in a `build.rs` or `main.rs` and writing the output out to a
file, consider having the code generator pass the tokens through [rustfmt]
before writing (either by shelling out to the `rustfmt` binary or by pulling in
the `rustfmt` library as a dependency). This way if an error occurs in the
generated code it is convenient for a human to read and debug.
Obviously, no kind of hygiene or span information is preserved when writing the
output to a file.
