Yes, it's that simple. You don't need to explicitly deallocate objects
that are used via RefPtr.

But this question is more about how the TextBuffer uses Tags.

If you would like to avoid creating a new TextTagTable, if you think
that would be more efficient, and if it is possible because there are
not so many changes, you could just remember the TextTags and change
them via the TextTag methods.
http://gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1TextTag.html

But if you create new tags, I don't know whether the TextBuffer will use
a new tag just because it has the same name as a previously-used tag.
You might need that. A small test case should show if it works.
