[PATCH] Fixes deactivate-mark issue when expanding selection to text-objects

[Tim Harper]

When CUA mode is active, commands such as viw, viW, vis, etc. would
exit visual mode because cua-mode, on activation, sets deactivate-mark
to t, and deactivate-mark isn't protected by save-excursion. This change
prevents that, and therefore fixes this issue.
