I won't change the behaviour of SIGINT in tinc 1.0.x. But this is fixed in tinc
1.1, there Ctrl-C works as expected. It also makes it much easier to debug; you
can for example just get log output for any log level from an already running
tinc daemon using this command:

tinc -n <netname> log <loglevel>
