Related problem

Nushell currently does not print anything when a program is terminated by a signal:

> echo "int main() { asm("ud2"); }" out> sigill.c
> gcc sigill.c -o sigill.out
> ./sigill.out
> # *crickets*

> echo "int main() { int v = *((int *)0x0); }" out> sigsegv.c
> gcc sigsegv.c -o sigsegv.out
> ./sigsegv.out
> # *crickets*

This could be okay if you have the exit code displayed as part of the prompt, but if you don't then it looks like everything completed successfully.

By contrast, Bash tells you what went wrong:

$ ./sigill.out
Illegal instruction
$ ./sigsegv.out
Segmentation fault

Describe the solution you'd like

If a signal is the reason a program exits prematurely, print the associated comment so the user is aware of the problem (available at https://man7.org/linux/man-pages/man7/signal.7.html "Standard signals" table), or the same for the Windows equivalent. This can be retrieved on nix with ExitStatusExt::signal.
