I will drop these hush patches.

Further testing shows that they don't really fix the problems.

Looking closer at the current hush code I think it's a waste of time
to try fixing these things; we should rather throw it away and
re-import a recent version from BusyBox, which would also bring a few
nice features like shell functions and the like.

Best regards,
