Right, so I wouldn't be in a hurry to change existing calls. If you're
editing an ereport call for some other reason, it's fine to remove the
excess parens in it, because you're creating a backpatch hazard there
anyway. But otherwise, I think such changes are make-work in themselves
and risk creating more make-work for somebody else later.
