Brad,

I hadn't thought about that.  We probably should iterate from 0,
although I think anyone who relies on that behavior is asking for
trouble, since the spec doesn't say anything about iteration order.

Attached are patches to char-set-lib and to string-lib.  The latter
adds `string-concatenate-reverse' and its shared variant.

Ben

PS:  The permissions are too tight on `list-lib' in the webdav
directory.
