+- Guards on `-c CONDITION` usage to attempt to be more user friendly.
+  Bogus JS code will result in this:
+
+        $ bunyan portal.log -c 'this.req.username==boo@foo'
+        bunyan: error: illegal CONDITION code: SyntaxError: Unexpected token ILLEGAL

+  And all CONDITION scripts will be run against a minimal valid Bunyan
+  log record to ensure they properly guard against undefined values
+  (at least as much as can reasonably be checked). For example:
+
+        $ bunyan portal.log -c 'this.req.username=="bob"'
+        bunyan: error: CONDITION code cannot safely filter a minimal Bunyan log record

+            this.req.username=="bob"

+              "v": 0,
+              "level": 30,
