@@ -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.
It permits any number of arguments;
