Parse back-references in comments of tcp-check expect rules. If references are made, capture groups in the match and replace references to it within the comment when logging the error. Both text and binary regex can caputre groups and reference them in the expect rule comment. [Cf: I slightly updated the patch. exp_replace() function is used instead of a custom one. And if the trash buffer is too small to contain the comment during the substitution, the comment is ignored.]
