feature request: simple hashbang for executable scripts

[j kalbhenn]

scripts of other languages usually need just one line to specify the 
interpreter:

    #!/usr/bin/myinterpreter

but with guile we have to add a final !#

    #!/usr/bin/guile !#

    or even

    #!/usr/bin/guile -s
    !#

in my opinion, this is not ideal. from my perspective as a guile user this 
seems to be unnecessarily inconsistent and complicated.
