--raw outputting hex/binary data

The documentation is schtum about this also, so I'm not sure, but is `--raw FILE.txt` supposed to output data that appears to be in binary/hex? I took "output raw data" to mean plain text results, as opposed to the HTML of `-o`. What form is `--raw` meant to output data in?

Start by locating the CLI handling for the `--raw FILE.txt` option and checking what output it produces for binary or hex-looking data. Confirm the intended output form, then update the relevant documentation so the behavior is explicit and verify the example is accurate.
