pytype: ignore some signature mismatch in registrar pytype is grumpy about a sub method having a different signature than the one we use here. pytype error: internalmerge: Overriding method signature mismatch [signature-mismatch] Base signature: 'def _funcregistrarbase._extrasetup(self, name, func) -> Any'. Subclass signature: 'def internalmerge._extrasetup(self, name, func, mergetype, onfailure = None, precheck = None, binary = False, symlink = False) -> Any'. Parameter 'mergetype' must have a default value.
