Putting an interactive command in the middle of a pipeline is
generally not going to work. Vim in particular is pretty aggressive
about trying to grab a terminal, which will result in processes
getting SIGTT* because they don't have foreground control of the
terminal they're trying to use.
Following Daniel's response I tried:
% </dev/null vim | { :|:; cat }
Vim: Warning: Output is not to a terminal
Vim: Warning: Input is not from a terminal
and although vim did open, upon exiting from it and returning to the
command line ZLE is very confused. Even a hard reset of the terminal
emulator didn't fix it, the stty settings were hosed.
