Unfortunately, $pipestatus is not working as advertised.

See this thread from 2011:

http://www.zsh.org/mla/workers/2011/msg01394.html

In particular

http://www.zsh.org/mla/workers/2011/msg01396.html
http://www.zsh.org/mla/workers/2011/msg01470.html
http://www.zsh.org/mla/workers/2011/msg01475.html
http://www.zsh.org/mla/workers/2011/msg01476.html

The patch mentined in msg01476 is here:

http://www.zsh.org/mla/workers//2011/msg01472.html

But it didn't resolve the issue, so I never committed it.

The long and short of it is that pipestatus only works reliably when
all the commands in the pipeline are external programs.
