+	* doc/manual.xml.head, init.h: Doc fixes and updates concerning hooks
+
+	- Add reply-hooks and send2-hooks in lists they miss.
+	- Fix that they all take full patterns, not only regexps.
+	- Note interaction with $default_hook.
+	- Enumerate them in execution order/increasing priority.
+	- Add iconv-hook, remove a duplicate charset-hook.
