Yep, I know ('twas from Olaf Hering, right ?). Nevertheless, both should 
be close if not identical.

Ok, I've stripped the new ash of all new features, so that now the old 
and the new version are identical in respect to the supported commands.
Only two minor things:
- 'type' is a new command (that was too ingrained within the shell 
itself so it couldn't readily stripped out)
- 'lc' is gone (I've no idea what it did in the first place, so it 
should not be a big deal)

Doesn't help much with the patch, though; uncompressed it's still some 
600k. Nevertheless this update should be done as the old ash wasn't even 
64-bit clean.

And it would cut down our patch-list for klibc by quite a bit :-)

Cheers,

Hannes
