It doesn't look like jc suffers from this bug since the regex match is greedy:

    % echo '2001 (my (file) with) S 1888 2001 1888 34816 2001 4202496 428 0 0 0 0 0 0 0 20 0 1 0 75513 115900416 297 18446744073709551615 4194304 5100612 140737020052256 140737020050904 140096699233308 0 65536 4 65538 18446744072034584486 0 0 17 0 0 0 0 0 0 7200240 7236240 35389440 140737020057179 140737020057223 140737020057223 140737020059606 0' | jc --proc

Edit: looks like I can tighten up the signature matching regex for the "magic" syntax per the issue found above. The greedy regex matching for the parser does seem to work fine, though.
