+~~~~~~~~~~~~~~~~~~~
+
+In the original implementation availible config option, which are removed.
+
+msg-hook: This is a text message that is output if the execution of
+ one of the external hook programs fails. There is a built-in
+ default message if none is specified.
+ This is removed, because I don't see this is necesarry and it's
+ not a good idee to pass a user provided string direkt in an
+ format string.
