[U-Boot] [PATCH 1/2] hush: Treat trailing || and && as incomplete statements

I really appreciate your patches.  But after having spent some time on
hush bug fixes myself (I submitted a few patches some time ago - to
kill them later when I learned I was just chiseling at the top of
somce iceberg) I seriously doubt if it makes senxe to try fixing the
many, many bugs in the old version of hush that is included with
U-Boot.

You may have a look over the fence at what Barebox fixed in this area,
but the result will probably be the same.

I fear that such patches, while fixing a nasty problem here and there,
will create other and maybe even more nasty problems in unexpacted
areas.


My suggestion is to save such efforts, and rather spend the time on
adating a more recent version of hush to U-Boot; getting things like
shell functions or backtic evaluation would be more than welcome to
many of us, I guess.

Best regards,

Wolfgang Denk
