Alan Diener <[email protected]> found a display bug in -svy: tabulate-
when BRR is used for variance estimation:

-svy: tabulate- is incorrectly ignoring the -se- and -ci- options for
reporting results when the BRR variance estimator is used.

We have figure out why and will have this fixed in the next ado-file update.
