0000122: Command line arguments

Hi,

I think I have found a small bug with the command line argument handling.
OCaml 3.00 shifts the Sys.argv command line arguments when invoked as
script:

ocaml <scriptname> a0 a1 ...

The script sees Sys.argv.(0) = "<scriptname>"; Sys.argv.(1) = a0 etc.
Well done. But Arg.current is not adjusted; it contains still the
number of already parsed arguments (here, !Arg.current = 1). I think
that Arg.current must be re-initialized to 0 after the arguments have
been shifted, otherwise the first argument(s) will be skipped if the
Arg module is used to parse the remaining arguments. In this example,
a1 is the first argument which is parsed by Arg.
