Please, please, someone fix this.  All the underlining causes a burning in my
eyes.  Ow. Burning.  Help.  So ugly.

Proposed Patch

Maybe you could try out whether that patch satisfies you? In single-click mode,
it will turn the cursor into a hand if when it is over a row and only hover the
row under the cursor.

Proposed Patch #2

Should improve hover experience. Don't request redraw of whole widget, just
emit "row_changed" on rows which experienced an underline toggle.

Reminder:  If the list view's behaivor in single click mode is changed in
nautilus is changed then it needs to also be changed in file-roller and
gnome-search-tool, too.

+leave_notify_callback (GtkWidget *widget,
...
+		gtk_widget_queue_draw (widget);

Why call this instead of emitting row_changed.

fm_list_view_click_policy_changed (FMDirectoryView *directory_view):
this doesn't emit row_changed if view->details->hover_path is set.

Proposed patch #3

Good catch.

Thanks for pointing this issue out. Dennis, Paolo, is this OK with you? Do you
still have enough time to adapt the search tool and file roller?

file-roller is fixed now.

Paolo: Great! Don't forget gThumb :).

I have created a patch on my local version of gnome-search-tool.  Please let me
know when the nautilus changes are applied and I will apply my patch to
gnome-search-tool.  Thanks.

I added some protection against the hover_path going stale (due to deletes or
something) and made sure to emit row_changed in policy_changed. 

The cursor unsetting didn't work, as it was unsetting the curson on a different
window. Also i added some protection against non-realized widgets in
policy_changed, since it was giving critical errors.

I checked in a patch which fixes this.

Dennis, you can commit your patch now.

I applied the patch to gnome-search-tool, so its single click to activate
behaivor should match nautilus.
