[Reportbug-maint] Bug#695219: reportbug incorrectly says "Report has not been sent yet" after SIGINT sent to process group

[Vincent Lefevre]

[also sent to 683671 at b.d.o since this concerns dash; for reportbug,
one should do a test with bash as /bin/sh to see whether reportbug
is really buggy or if this is just a consequence of the dash bug.]

I couldn't try because the Debian BTS doesn't have a test system
(due avoid creating a dummy bug report), but a Ctrl-C in Mutt
also sends a SIGINT to the whole process group (as expected),
even when one doesn't quit Mutt and Mutt terminates normally.
So, even if the problem is "fixed" (avoided) in Emacs, the real
problem still exists.
