Sorry, I was not enough clear. I meant that bash restores the trap
to the behavior at the time that bash was called. But it seems to
be something different, something like if SIGINT is ignored when
bash is executed, a "trap command INT" has no effect unless both
bash and its child receive a SIGINT. Now, this behavior is a bit
strange, maybe a bug.
