I remain *interested*, but I'm tied up with a bunch of deadlines and not 
a proper build environment to test under... For reference it was killing 
me with regards to modprobe, but I suspect it would have an impact on 
other shell tools such as sed/awk, so it's definitely worth pushing 
(sorry, just realised this is the uclibc list, the effect originally hit 
me upstream in busybox)

Can someone else ack that the changes have benefit?

Thanks
