It was obvious (to me) what this code is doing.  But I will not accept it.
Creating files called "*" on disk and then removing them, just to be lazy
in your shell programming, is too ugly for me to handle.

Oy.  Way too fragile for my taste.  Acceptable kludges would be
saving/restoring the caller's value in the function, or forking a subshell
(i.e. put ( and ) around the recursive call).
