@@ -20,6 +20,7 @@ This command joins each of its arguments together with spaces after
 trimming leading and trailing white-space from each of them.  If all of the
 arguments are lists, this has the same effect as concatenating them
 into a single list.
+Arguments that are empty (after trimming) are ignored entirely.
