I don't know what you mean.  If the file starts with "#!"  then that
certainly does give a very strong hint as to what the file is.  In the
same manner, if the file starts with "%!"  then you know it's probably a
PostScript document (and that _is_ in /etc/magic).

If it's at the start of the file and if any utility other than "file"
looks at it to find out what the file is then it's a magic number as
far as I'm concerned.
