The gnome-terminal doesn't store the "Select-by-word characters" preference
when it is changes from the preferences dialog.
1. start a gnome-terminal
2. right click on terminal to bring up context menu
3. Select 'Preferences...'
4. Add an underscore to the beginning of the "Select-by-word" characters.
5. Click "OK"
6. Exit the gnome terminal
7. Repeat steps 1 through 3
The underscore that was added in step 4 has not been saved.
hmmm - actually gnome-terminal seems to ignore the contents of "wordclass" in
.gnome/Terminal altogether. Even with an empty "wordclass=" line in the config
it still uses the default word chars.
This appears to be fixed in gnome-core-1.2.4-3 (although I can confirm seeing it
in the stock 7.0 gnome-terminal)
