What if the string entered into the text filter widget does not match any window
titles - won't |showing_selection_widget_| be false in that case?

[varkha, 2016/08/24 16:53:54]

No. |showing_selection_widget_| is indicating visibility of the text filter
rather than "selection widget" (aka WindowGrid::selection_widget_|. Name reuse I
guess. I will rename the variable to reflect that.
