In other files I have seen it as:
/* globals CallsHandler, CallScreen, Contacts, ContactPhotoHelper,
                KeypadManager, kFontStep, LazyL10n, Utils, Voicemail */
but I guess you prefer it as:
/* globals CallsHandler, CallScreen, Contacts, ContactPhotoHelper,
                  KeypadManager, kFontStep, LazyL10n, Utils, Voicemail */
I mean, with 2 spaces deeper taking "CallsHandler" as the reference point. Am I right?
