chore(invalid_regex): correct capture-reset wording#69
Merged
Conversation
Verified against nginx 1.27: a non-matching map entry leaves the request's numbered captures untouched (only a match resets them), while a failed if-condition evaluation clears them outright — so a $N inside a '!~' block is plain empty, never 'a stale value from a previous match'. Comment/message text only, no behavior change.
