Maybe the online help for tabstat contains an error?

Description
...
With the by() option, tabstat resembles "tabulate varname,
summarize(varlist)" in that both report statistics of varlist for the
different values of varname. tabstat allows more flexibility in terms of
the statistics presented and the format of the table.

--snip--

tabulate varname, summarize(varlist) or tabsum does not take a varlist for the summarize option.
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.
