Hi,

I can't invent anything better than -where <at> filter.json and <at> is also
 used for the same purpose by curl and Oracle PL/SQL so we could call it as
a  de facto standard.

Which one should win if -spat and -where @... are both feeding a spatial
filter? Should it be "either-or", or "both" as a combined filter with AND in
between?
