From 92136757bfd20563999b0e1cf3f05685b60da6bd Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Mon, 30 Sep 2013 20:39:59 -0500 Subject: Proper support for revoked signatures The 'valid' column wasn't quite right. Add a new 'revoked' column that works similar to the one we have on keys and use it instead, properly parsing the output from `gpg` signature data and looking for the magic prefix string.
