So does send-break (using e.g. ESC-x send-break RET):

torch% $(
cmdsubst> 
execute: send-break_
zsh: parse error near `$('
torch% 

} That's a completely different kettle of fish --- push-input is basically
} a hack to try to convince the line editor we've left it so we can start
} again.

Yes it's a hack, but it's the same kettle -- push-input uses send-break,
and send-break is supposed to be a simulated interrupt for cases where
the TTY intr character is not set.

So either send-break should actually set ERRFLAG_INT, or we need a third
error flag for simulated interrupts.
