I don't remember exactly which ones there were, but when I did some more
comprehensive research a while back, there were several major ones that
weren't supported by dash. Since one of the practical points for this
whole exercise is to let people use dash as /bin/sh, since it can be much
faster, that seemed like a good argument against it.
