We want to keep an error if it _includes_ any lines in a given patch. We also want only the first such line, since it likely includes more than one (this singularism was implicit before, because each line was only passed through once)

Thank you sir! No rush, we have a workaround in place :-) |

Purpose
Currently, if a changeset appends a bunch of logic to a large method, and the resulting method is "too complex", rubocop will complain, but pronto-rubocop will not notice. This is because we're comparing the
offense.lineagainst the patch to see if that line is part of the changes being checked.. but theoffense.lineis actuallyoffense.location.first_line, which can be outside the changes, despite the violation being introduced.Implementation
selecttodetect- the prior implementation only ever hit a given offense once, since it only traversed each line-number once. But now it's possible (likely) to hit the same offense multiple times on consecutive lines, and we're only interested in the first time the offense was affected.patch_cop_spec.rb.
