Ah, indeed.  I've only looked at the patch where this context hasn't
been visible.

But are you sure that changing the GNU Emacs version of
`TeX-activate-region' from a no-op to the above has no undesired
side-effects?  I mean, it's also used at some other places in latex.el,
tex-info.el, and context.el.

Ok, then let's use that.
