Repeated patterns are FP-prone

[tripleee]

What problem has occurred? What issues has it caused?

@ThatRyanPerson reports hundreds of FPs for "stream" alone: https://chat.stackexchange.com/transcript/11540?m=56131137#56131137

The chat transcript has another case slightly earlier where "cat,cat,cat,cat" matched a watch which is supposed to catch a list of exams (I think it was).

What would you like to happen/not happen?

Probably refactor these regexes to avoid this specific source of FPs.
