In the manual, for
etc. it doesn't mention the case of when word is null.

Furthermore, for
$ a=(123 456);echo address@hidden/#/1}
1123 1456

one might have never thought this possible, due to the manual only


              ...If string is null, matches of pattern are deleted and
              the / following pattern may be omitted.
