As it happens, cygwin uses ash as its default noninteractive shell,
so I certainly want to support ash.

I did a lot of work porting ltp to run under busybox's ash, so
I'm very sympathetic to these issues.  Maybe I'll even test
using busybox ash as the shell, what the heck.  It's a bit low
on the priorities, though.
