Note that we do keep ignoring the gpg_path configuration option, though, to avoid breakage of existing installations. It is ignored like any other unknown configuration option, but we at least document that it is ignored so that people who find it in their legacy configs can know that it's safe to drop. signed-off-by: Daniel Kahn Gillmor <dkg@fifthhorseman.net>
