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.
