Track the parser status both per file (file_status), such that

we can for example skip rendering on FATAL parsing errors,
and globally (exit_status), such that we know what to return.
Without this, following files produced no rendered output
once a single file suffered from a FATAL error.
Bug reported by kristaps@, fix by me.
