Strictly speaking, a varname is a special case of a varlist (see -[P] 
syntax-). However, I can see how the online help for -tabstat- might 
confuse people who do not know this. Perhaps the next version of the 
documentation should refer to

tabulate varname_1, summarize(varname_2)

in order to be clear.
