Rostislav Skudnov 204c7fb229 ash: exit after subshell error when errexit option is set

When "set -e" option is on, shell must exit when any command fails,
including compound commands of the form (compound-list) executed in a
subshell. Bash and dash shells have this behaviour.

Also add a corresponding testcase.
