ADD ABILITY TO EXECUTE FILES WITH "#!" MAGIC NUMBER

ADD ABILITY TO EXECUTE FILES WITH "#!" MAGIC NUMBER

	If the first two characters of a file are "#!", this constitutes
a "magic number" which indicates that the file is a shell script and that
the character string following the "#!" should be executed, and that the
shell script itself should be used as stdin for the program executed.
