OK, *now* I write:

	spam () { for i in "$@"; do echo $i; done }

and if I run

	spam "a b" c

I get
	a b c

Similarly, if I leave out the double-quotes, then

	spam "a b" c

produces
	a
	b
	c

It looks like the arguments to functions aren't getting passed quite
right.  This looks familiar; is it one of Chet's
I-have-fixed-this-and-sent-the-patch-to-Brian things?

This series of problems was generated by my attempts to fix the
problem Anders Ellefsrud <anders@ifi.uio.no> noted when he posted a
*corrected* autoload function.  (Silly me, I only implemented the
load, I didn't have it *do* anything!)

BTW, the current candidate for autoload is:
	autoload() {
	   eval $1 '() { args=$@ ; . '$2' ; set -- $args ;  return '$1' "$@" }'
	}

It really should check to see that it has two arguments; I got really
confused when I kept forgetting to provide the filename to
autoload....  Also should check $2 for a leading slash and prepend
$PWD/ if it's absent.

You need the return in case the autoloaded function returns something;
the "$@" is what this message is about; it *should* be right, although
it doesn't work as expected (hence this posting).

Bryan, you asked something about "what is autoload", essentially.  I
think we're probably all basing our discussion on what we've picked up
from emacs' autoload.  I'll spare you the agony of reading the output
of C-h f autoload   :-).
