Tests RE behavior of ERR_EXIT

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

Changed a set of tests from success to xfail.  Anyone have ideas of
why these aren't working?

If I change the ( subshell ) constructs to use
$ZTST_testdir/../Src/zsh -fc then they all correctly exit on nonzero
status as expected.

Aside, should 'setopt err_return' in the nested function test be using
localoptions ?
