Given a file

Foo

---
#!<interpreter> <options>


the kernel changes the command line


Foo <args>


to


<interpreter <options> Foo <args>


Once you know that all should be clear.


Hint: the -f option in csh takes the next "word" as the name of the file
to run.  The first verstion gives "csh -fb blah args" while the second
gives "csh -f -b blah args" and csh tries to run the script "-b".


As far as I know all unices (?) do it this way.
