code review 12142043: fmt: treat \r\n as \n in Scan

fmt: treat \r\n as \n in Scan
When scanning input and "white space" is permitted, a carriage return
followed immediately by a newline (\r\n) is treated exactly the same
as a plain newline (\n). I hope this makes it work better on Windows.

We do it everywhere, not just on Windows, since why not?

Fixes issue 5391.
