 @defun add-to-history history-var newelt &optional maxelt keep-all
-This function adds a new element @var{newelt}, if non-empty, to the
-history list stored in the variable @var{history-var}, and returns the
-updated history list.  By default, the list length is limited by the
-value specified by @code{history-length} (described below), but the
-optional argument @var{maxelt} overrides that.  The possible values of
address@hidden have the same meaning as the values of
address@hidden

-Duplicate members are removed from the history list, if
address@hidden is address@hidden
-
-If @var{keep-all} is address@hidden, even an empty or duplicate
address@hidden element is added to the history list.
+This function adds a new element @var{newelt}, if it isn't the empty
+string, to the history list stored in the variable @var{history-var},
+and returns the updated history list.  It limits the list length to
+the value of @var{maxelt} (if address@hidden) or @code{history-length}
+(described below).  The possible values of @var{maxelt} have the same
+meaning as the values of @code{history-length}.
+
+Normally, @code{add-to-history} removes duplicate members from the
+history list if @code{history-delete-duplicates} is address@hidden
+However, if @var{keep-all} is address@hidden, that says not to remove
+duplicates, and to add @var{newelt} to the list even if it is empty.
