    [PATCH 161/277] [EVAL] Check exit for eval NSUBSHELL

    Example:

    $ dash -c 'set -e; (false); echo here'
    here

    With this commit, dash exits 1 before echo.

    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.
