@Roman: By pure coincidence i discovered that ctrl^c+SHIFT _does_ terminate an application for me (i ran ConEmu + powershell core). Does that work for you too with ConEmu+cmd or ConEmu+farmanager?
Yes, the behavior is more consistent with recent Wine and the only difference between Windows and Wine is just this in ConEmu: Ctrl+c shows "c" and Ctrl+C (c with shift key) actually terminates the command/application.
There is another difference that Ctrl+c terminates cmd instead of clearing prompt line, but that is bug 27605.
Ok, maybe send patch in after code freeze? Better then let it rest here for years ;)
