There was a problem hiding this comment.
A detail: I would swap the if and else blocks. It allows you to get rid of the ! in the condition for better readability.

I modified the test cases
test_up_to_match_offset_option_suppress_matchedaccording to the issue #7052 and also the testtest_up_to_match_negative_offset_option_suppress_matchedbecause the output was different with the GNU implementation.The code should fix the bug:
In case of positive offset: the code checks if the offset is greater than 0, so the last line should be skipped
In case of negative offset: when the regex is matched, the first element of the buffer should be deleted and the current line inserted.
