Bug #745: subshell redirections which read stdin become unstoppable, interrupts hit the wrong process

<pre>
sellout:~> ssh -t metropolis bash
metropolis:~$ cat <(cat /dev/stdin) | cat
^CConnection to metropolis closed.
zsh: exit 255   ssh -t metropolis bash
sellout:~>
</pre>

A ^D to attempt to get an EOF to the inner-most cat fails too, and I suspect it shouldn't.

The actual command I used was

@metropolis:~$ comm -13 <(sed -e 's,root_i386/,,') wsdiff.log | wc -l@

With which I now find that, without a wsdiff.log, may or may not screw up further input to a shell which may or may not be at the top level (I ended up with the shell only echoing every other character typed, but I'm not sure how/why).
