click+Ctrl doesn't work anymore to do single dots,
don't know when it started but i noticed it in r20809 (now using r20821 and the bug is still present)
It does work with pen tool if you select straight line modes (the last two mode icons).
I confirm it needs a status bar message cleanup in tools-switch.cpp.
I think this is a feature, not a bug ;-)
