I know. But it has problems:
- if there's a nested use of set-transient-map (e.g. C-u), your code will
deactivate the mark even tho we're not finished with C-x TAB.
- it relies on internal details of implementation of set-transient-map.
- now C-x TAB does not deactivate the mark any more :-(

Could be, tho the two tests need to be different.
Another option is to move the deactivation into the exit condition.
Yet another option is to change C-x TAB so that it uses (mark t) when
I'm not sure exactly how the deactivation should behave, tho:
- The current behavior seems wrong: C-x TAB does use the region, so it
should "consume it", so C-x TAB right right right up should end with
a deactivated region.
- But should the region be highlighted *during* C-x TAB? If yes, then
we have a conflict with the previous point, since just before hitting
`up' the region would still need to be highlighted, so it'd be counter
intuitive to deactivate the region right between when the user hits
`up' and when we run the corresponding `previous-line' command.
So I think that the region should *not* be highlighted during C-x TAB.
Which implies using (mark t).
