`mime-display-header-hook' before insert "\n"'; add description about
current point when `mime-display-entity' runs
`mime-display-header-hook'.
`mime-view-entity-body' in header and body of each entity.
-** Run `mime-display-header-hook' before insert "\n"
+** Behavior change about `mime-display-header-hook'
+
+Function `mime-display-entity' runs `mime-display-header-hook' before
+it inserts "\n".
+
+In addition, now it is cleared that current point means beginning of
+header when `mime-display-entity' runs `mime-display-header-hook'.
+Therefore header-presentation-method must not change current point.
