Currently, hitting the keyboard shortcut for the Print command sends whatever is in the current window to be printed. This happens by accident often enough to be a significant annoyance.

This simple patch to IOBinding.py makes the print command pop up a simple yes/no dialog which asks "Are you sure you want to print the window's contents?".

Some colleagues and I have been using this for several months to our satisfaction. It has saved me from printing by accident 3 times already.
