[REQUEST] make <c-c> capturable with RawKey hook

[eko234]

Feature

Make hook <scope> RawKey <c-c> correctly capture the event when is pressed.

Usecase

Hi, I understand why does what it does, but I think when some plugins that use long running processes want to be somehow resilient to sigint propagation, this would be very handy, there might be better ideas to work this around, like having better process management, I don't know if this is something that will be improved in the future, thanks!

asynchronous subshells already ignore SIGINT by default, see 7b93567 (Reset SIGINT handler in background processes, 2024-03-29) and others

To elaborate, if your plugin does something like this:

nop %sh{
    (
        sleep inf
    ) >/dev/null 2>&1 </dev/null &
}

the sleep process will not be cancelled by <c-c>

The current way to avoid SIGINT for long running processes is to use setsid to get a new process group, it is not strictly posix but has been working fine for now.

Oh, I see, thank you, I will check it out to see if it fits my usecase, but I still think it would be useful to capture C-c, maybe not remap it, but capturing would be nice.
