Exitcode is 0 when killing a cygwin initiated process via taskmanager

[-]

Hi all,

I have a script running banana after killing a process (rsync, but
that is unimportant) through Taskmanager (End process in process tab).

It is, that the killed process exits  immediately with exitcode 0 (!)
and the bash script itself continues, which can lead to havoc because
not knowing something was canceled (continuing to mive directories
etc).

Win7, CYGWIN_NT-6.1-WOW64 Gizmo-PC 1.7.33-2(0.280/5/3) 2014-11-13
15:45 i686 Cygwin

simple to reproduce:
START script.sh
#!/usr/bin/bash
less some_file
echo "result: $?" >| erg_file

erg_file contains: result: 0 after killing less through process taskmanager

Any idea how to solve (get the "canceled" exit code? Remember: The
script continues like a normal finish of the command)

Thanks
