...if executed in a dot script, that is (in case that wasn't clear from
the subject line and the code examples).
Another datapoint: the same phenomenon occurs if the SIGINT trap is
unset from within the trap itself.
$ trap 'echo "unignoring SIGINT"; trap - INT; kill -s INT "$$"' INT
$ kill -s INT "$$"
unignoring SIGINT
(interactive shell exits. Expected behaviour: return to command prompt
with exit status 130)
