First thank you for this great text editor.
My problem is that when I type without looking at keyboard i'm often off-by-one.
Most of the time it's possible to correct, however Clipboard overwriting is not reversible.
So I often press CTRL-X instead of CTRL-S. Same problem with CTRL-C , CTRL-V
When some text is selected, Cut/Copy make sens so i'll accept it as my fault.
However when nothing is selected, ST2 behavior is to clear clipboard,
while other text editors simply ignore the copy/cut command (np++ for example).
So my suggestion would be:
When selection width is zero, ignore clipboard command rather than overwrite with nothing.
Thanks you very much.
