I don't see what stdin has to do with it. A script as shown above
will simply cause the kernel to run `/usr/bin/emacs /the/script/file/name'
with the same old stdin, stdout, stderr, ... so Emacs will simply
load the script as a file to be edited.
If we don't want to add a new parameter, we could simply recognize
emacs -batch <file>
as a shorthand for
emacs -batch --load <file>
since (after all) just `emacs -batch <file>' doesn't make much sense
except for the very rare case where we want to execute what's in
the `local variables' section of the file.
