using super to find a syntax problem in a large .sup file

[chrismo]

super -i line -j -c '
    values {raw: this, parsed: parse_sup(this)}
    | where is_error(parsed)
    | cut raw
  ' broken-file.sup

• Reads each line as a raw string (-i line), bypassing the SUP parser entirely
• parse_sup() tests each line individually, returning error values instead of crashing
• First error in the output is the real problem; subsequent errors may be parser state bleed

Next release after 0.1.0 should have a fix for this.
