Bram,

I'm a member of the maintainer group for Debian's Vim package.  Attached
is a patch for runtime/scripts.vim to address the bug reported in
<http://bugs.debian.org/309859>.

This patch includes support for detecting #! lines for Lua scripts.
I've also added support for scripts which use

#!/usr/bin/env program [path/args]

instead of

#!/usr/bin/program [path/args]

James
