Like Nick Cox said, it is documented, although this is the first I've heard 
of it.  I actually rather like the logic of doing it this way:

commandname varlist, options, sample selection and weighting

That seems more natural and easier to read to me than mixing together the 
varlist and the sample selection/weighting info.  For that matter, if I was 
writing Stata from scratch, I suspect I would have just made the -if- and 
-weight- parameters part of the options section of every command; again 
that seems more natural to me.
