GNU Parallel Bug Reports env_parallel does not respect exit code from functions

[Stefan Andres]

Hi,
the manual states:

EXIT STATUS
       Same as GNU parallel.

But it seems that is not true:

$ parallel --version
GNU parallel 20160922
Copyright (C) 2007,2008,2009,2010,2011,2012,2013,2014,2015,2016

$ myfunc() { exit 1; }
$ . env_parallel.bash
$ set -x
$ parallel myfunc ::: one two; echo $?
+ /usr/local/bin/parallel exit ::: 1 2
[...]
+ unset PARALLEL_ENV
+ echo 0
0

The unset PARALLEL_ENV; line in env_parallel.bash just overwrites the
parallel exit code.

The direct exit code works just fine:

$ parallel exit ::: 1 2; echo $?
2


Regards,
  Stefan
