[PATCH] [RFC] Reset pipestatus in zleread

[Daniel Hahler <genml+zsh-workers@thequod.de>]

From: Daniel Hahler <git@thequod.de>

What do you think about this?

I am looking at $pipestatus in my prompt precmd function, so that with
"false | true" I would still get an indicator that (something in) the
command failed (since $? (status) is 0 in this case).

However, with e.g. "foo=bar" (executed via execsimple) $pipestatus gets
not reset.

This patch resets it in zleread always.
