dia0.96pre: Minor text bug

[christian ridderstrom gmail com]

I've noticed two strange things when editing text.

Here is the first thing:
1. Open the diagram
        http://www.md.kth.se/~chr/dia/bug1.dia
2. Click on the text
3. Press END to get at the end
4. Press BACKSPACE to try and delete the last character

   Nothing happens, except it says that the diagram has been changed

5. Press BACKSPACE again.

   This time the last character is deleted.

The second thing I'm unfortunately unable to Here is the second thing: 
Sometimes when I tried deleting the last character, some unprintable 
characters showed up instead. I'm guessing they are unprintable as it 
looked like a small box.

Unfortunately I'm not able to reproduce this consistenly, but I'm hoping 
the first bug is related.

cheers
/Christian
