st: Undocumented limitation of describe (and hence -ds-) in Stata 10?

I found out the hard way that the r(varlist) macro result returned by -describe, varlist- (and hence -ds- and Nick Cox's -ds3-) is limited to 243 characters, at least on my computer running Stata 10. Is there a Stata setting I need to change? The help page says something about -maxvar-, but this doesn't seem like it should matter, and in any event doubling -maxvar- has on effect on this result. If this is not a settings issue, has it been fixed in Stata 11? Thanks.
