For some reason, its value in the Google style we use is 80... except for Objective-C, where it's 100, which led to things like: https://hg.mozilla.org/mozilla-central/rev/31bf68247e6e https://hg.mozilla.org/mozilla-central/rev/64ceb33533a4. There's probably a discussion to have about whether 80 is the right limit, but since it's what's used for everything except ObjC, let's roll with it. # ignore-this-changeset Differential Revision: https://phabricator.services.mozilla.com/D187409
