rules: accept revert commit titles that were elongated by git

[RaisinTen]

This change ensures that the commit message linter doesn't reject
revert commits that originally had commit titles with an acceptable
length but were elongated during the revert process by running
git revert.

If a revert is reverted, doesn't git turn that into Revert "Revert "...""? Maybe that changed or I am misremembering, but if it does, this should maybe account for that.

@tniessen you're correct about the generated commit title but it seems core-validate-commit is not able to parse the subsystem correctly in that case, so I guess support for Revert "Revert "..."" commits can be added in another PR?

@richardlau since you've been creating most of the releases for this repo recently, I thought I should ask you if you could give my npm account (https://www.npmjs.com/~raisinten) enough permissions, so that I can publish v3.16.1 with this change please? (I get this error when I run npm publish - 403 Forbidden - PUT https://registry.npmjs.org/core-validate-commit - You do not have permission to publish "core-validate-commit". Are you logged in as the correct user?)

@RaisinTen I've added you via

$ npm owner add raisinten core-validate-commit

@richardlau thanks, I've published v3.16.1! :-)
