tests/run-make/pretty-print-to-file/rmake.rs

// The "pretty-printer" of rustc translates source code into other formats,
// which is useful for debugging. This test checks the "normal" version of
// -Zunpretty, which should format the poorly formatted input.rs into a one-line
// function identical to the one in input.pp.
// See https://github.com/rust-lang/rust/commit/da25539c1ab295ec40261109557dd4526923928c
