You're right. Sorry, my mistake. The test is a bit too rigorous, it
now fails on every shell (which just had the effect that it never used
the zsh, which is why I never noticed the problem, of course). The intent
was to check for something else.

The test should have read (fixed in the next release :-):
*zsh*) $RM src/_autotst
$SHELL <<HERE
O="echo test"
exec 2>$DEVNULL 1>&2
\$O && echo test >src/_autotst
HERE
As to why it is just being tested on zsh, well, that's the only shell
that (ever) exhibited this (broken) behaviour.
