-The third argument FACE specifies the face to add.
-If any text in the region already has any face properties, this new
-face property will be added to the front of the face property list.
-If the optional fourth argument APPENDP is non-nil, append to the end
-of the face property list instead.
-If the optional fifth argument OBJECT is a buffer (or nil, which means
-the current buffer), START and END are buffer positions (integers or
+FACE specifies the face to add. It should be a valid value of the
+`face' property (typically a face name or a plist of face attributes
+and values).
+
+If any text in the region already has a non-nil `face' property, those
+face(s) are retained. This is done by setting the `face' property to
+a list of faces, with FACE as the first element (by default) and the
+pre-existing faces as the remaining elements.
+
+If optional fourth argument APPEND is non-nil, append FACE to the end
+of the face list instead.
+
+If optional fifth argument OBJECT is a buffer (or nil, which means the
+current buffer), START and END are buffer positions (integers or
markers). If OBJECT is a string, START and END are 0-based indices
into it. */)
