Really, this is what I would be happy with too. I have no problem with
bashisms in hush -- it's a 'Busybox-ism'. The problem I have is having
an ash that doesn't behave like an ash, thus encouraging people to
write scripts like:

cat <<EOF
#!/bin/sh

mkdir {build src bluurgh}

cd build || echo "WHY ISN'T SH BASH???"

EOF

then testing them with ash, it working fine and then being surprised
when it breaks for others.
