No, a Ctrl-C in

  zsh -c "info Emacs"; echo foo

interrupts info though it is interactive, contrary to what happens
with gdb and Emacs. It seems that the condition is that the command
traps the signal. One even has:

ypig:~> cat trap.sh
#!/bin/bash

trap 'kill -INT $$' INT
sleep 3
ypig:~> zsh -c trap.sh; echo foo
^Czsh: exit 130   zsh -c trap.sh
foo
