I found a problem with the patch on master:

  ~ $ {echo hello; echo world} | rev
  olleh  ;; "dlrow" is missing!

This happens because the way I'm copying output handles around results 
in EOF being sent to "rev" after "echo hello". To be fair, this didn't 
work correctly before either, but the problem was different. Prior to my 
patch:

  ~ $ {echo hello; echo world} | rev
  hello
  dlrow

(Only "echo world" is actually piped through "rev".) I'll try to come up 
with a fix in the next couple days.
