That would be OK with me; it's certainly less of a hack than what's
there now.  (I went back and forth about how much effort to put into
dealing with the colon syntax; I think the version I have in my patch
would be all right, but it's not perfect.)

Uh, why not

\crosstabview [ colV colH [ colD [ scolH ]]]

I see no particular reason that the existing abbreviation styles aren't
good.  In any case, forcing colD to be specified is kind of annoying ...
