- I forgot to compress xhtml files. fix that. - Stylistic change: remove unnecessary brace expansions - Don't repeatedly append to a file; run commands in a different scope and write all at once. Move Nu HTML validator filtering into a shell script: - Return a bad exit code if validation errors are found after filtering - Remove null-ish values from the JSON output; the final output *should* be an empty string, since nothing should be reported.
