Tweak pedantic description for occasional FPs

changelog: none

Okay this is getting a bit picky (you might even say pedantic). I think we need to be careful not use the pedantic category as cover-all for lints with any amount of false positives. Lints with a high degree of FPs should be nursery or restriction IMO. If the pedantic category were to yield, say hypothetically, over 50% FPs, it would just be too annoying to use at all (to be sure, "too picky for me" is not a FP).
