orca: read by word in firefox (ctrl+left) misses the first part of hypenated words

[Alan Jenkins]

Ubuntu 11.04
gnome-orca 3.0.0-0ubuntu2

1. Enable Orca screen reader
2. Open firefox
3. Type ctrl+L, google.com (i.e. go to google.com)
4. The tex box should be selected automatically (you will need to select it manually if you use NoScript though).
5. Type "press alt-tab".
6. Press Home - this will move back to the start of the text box, and abort Orca's attempt to read the Google Instant results.
7. Now press ctrl+left. The first word, "press", is read correctly. But press it again, and you hear "tab". Press it a third time, and you hear "blank".

Note: if you use ctrl+right to go *backwards* through the words, they will be read correctly - "tab alt press" . So the correct behaviour for ctrl-left would have been to read "press alt tab".
