+        * mh-junk.el (mh-spamassassin-blacklist, mh-spamassassin-whitelist): 
+        use mh-junk-background consistently in call-process calls.
+
+        * (mh-bogofilter-blacklist, mh-bogofilter-whitelist,
+        mh-spamprobe-blacklist, mh-spamprobe-whitelist): use
+        with-current-buffer so the right thing happens if
+        mh-junk-background is t.  (closes SF #1594802).
+
+        * mh-e.el (mh-junk-background): document that On value is 0;
+        t may be used for debugging.
+

         * mh-e.el (mh-draft-folder): Avoid starting sentence with "nil".
