Why is this an issue?

This rule template allows you to track the use of comments matching a given regular expression. Note that the regular expression must match the full text of the comment and will be executed in dotall mode (where the . character matches any character, including newlines).

For example, one can create a rule with the regular expression .*REVIEW.* to match all comments containing "REVIEW". To match REVIEW regardless of the case, the (?i) modifier should be prepended to the expression: (?i).*REVIEW.*.
