When you press Backspace you go into a mode where you edit the text, so that you can change the list of matches. Just about any character can appear in the matches (e.g., for line completion or when using omni completion). It's difficult to decide when to leave this editing mode. Also because you can make a typo, and expect Backspace to correct that. If the key exits completion mode you can't go back to what you were doing. > Actually, I've hit another bug few times already, unfortunately I can't > reproduce it.

If you find a way to reproduce this "undo line numbers wrong error" then I would very much like to see it. It's hard to fix something that I can't reproduce. -- How To Keep A Healthy Level Of Insanity: 5. Put decaf in the coffee maker for 3 weeks.
