Returns %TRUE if some text is selected; places the bounds
of the selection in @start and @end (if the selection has length 0,
then @start and @end are filled in with the same value).
@start and @end will be in ascending order. If @start and @end are
NULL, then they are not filled in, but the return value still indicates
whether text is selected.
