Nice idea, thanks! I was thinking that it won't work in all cases, but
see below. :)

Another nice trick, thanks again!

I thought that this wouldn't work here, because we already have double
quotes around - but looks like they are not needed at all. At least,
ksh does not do field splitting or glob expansion of $b in a=$b
case... So a quiet a few double quotes could be dropped now. Thanks
again!
