Bug description

When editing a toplevel script in emacs caml-mode,
auto-tabbing indents the shebang line and the directive
immediately following it if one is present.

Steps to reproduce

Create and auto-indent a toplevel script with a shebang line,
using emacs and caml-mode.

Additional information

The following code is a patch for caml.el.
It seems to work, but I'm not an elisp expert,
so it may be slow or otherwise suboptimal :(

;small addition to caml-compute-basic-indent
(defun caml-compute-basic-indent (prio)
(if (= 1 (line-beginning-position))
0
))

;new function
(defun caml-in-shebang-line ()
(save-excursion
(beginning-of-line)
(and (= 1 (point)) (looking-at "#!"))))

;one-line insertion into the COND form in caml-in-expr-p
(defun caml-in-expr-p ()
(let (...)
(caml-find-kwop ...)
(cond
((caml-in-shebang-line) (setq in-expr nil)) ;; maybe reset pos?
; special case for ;;
...)
...)
