+dnl default is one of:
+dnl   yes    -- enabled by default. user must explicitly disable.
+dnl   no     -- disabled under default, most, all. user must explicitly enable.
+dnl   most   -- disabled by default. enabled explicitly or with most or all.
+dnl   ""     -- disabled under default, most. enabled explicitly or with all.
+dnl
+dnl basically: yes/no is a hard setting. "most" means follow the "most"
+dnl            setting. otherwise, fall under the "all" setting.
+dnl            explicit yes/no always overrides.
