Text selections in gtk

[Mattias Grönlund <Mattias Gronlund sdf se>]

Hi

Just found something that I would call a bug in the text selection
handling in gtk.

Start testgtk and run the text test. Enter the following text:
Selection test
!!!

Then try to double-click on one of the '!' characters, just like
som sort of magic the word "test" get highlighted.
