Trying to get a better handle of HUSH shell expressions, this does not

I always just assumed this was a limitation of hush, but it's now
looking like a bug instead.
I haven't debugged into it, but I tend to stay away from hush these
days. When I've submitted a bug fix to this area I've been told that
we should upgrade wholesale instead, and I've haven't been up for that
task so far. http://lists.denx.de/pipermail/u-boot/2012-November/139841.html
That's a great conversation with Wolfgang, thanks for the reference.
Like you, I have tended to use hush carefully. It is similar to sh/bash,
but different enough that I never count on an easy port of bash script
fragments.
I noticed you asked for a reference to the original hush code that is
the origin for U-Boot's adaptation. I couldn't find a reply to that
question. I also haven't been able to find anything with a quick we
search. Do you know where it did come from?
Perhaps there is an easy, minor bugfix for this that would be palette-able.
I've been "afraid" of the hush code for a while. I don't think I want to
mess with it now. I'll just continue to work with what we've got, carefully.
Thanks again for your attention,
Jim
