+Subject: [PATCH] Fill panel width/height in custom/fit content modes when
+ flexible spacer is in panel
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The flexible spacer should always make the panel gain its maximum
+width/height; this implements that.
