This is incorrect.  The '#!' test for ascii input must be part of of
the standard libraries, and not just implemented in lua.c.  Otherwise,
a file that starts with '#!' cannot be loaded using dofile.  Surely
you are not asking that the interpreter use a different version of
dofile, are you?

Of course, another solution is to allow the use of '#' as another
comment start indicator, but that is not a serious proposal.
