SelectionEngine::SelMouseButtonDown change

[Jim Raykowski]

Hello,

I have uploaded a patch to gerrit for enhancement request bug 154211
to allow selecting a range between the current cursor position in the
document and the content position navigated to by shift + double-click
on a content entry in the Writer Navigator content tree. [1]

To make the shift + double-click behavior for x11 and qt5 the same as
gtk3, the patch changes the SelectionEngine::SelMouseButtonDown
behavior handling for single selection mode with KEY_SHIFT modifier to
select the entry in the list. The current behavior is no entry
selection is made.

Is there reason to not change this behavior?
