Tests how the variety of location values are handled.
Why location? Mostly because it is one tricky parameter. It is not
uncommon to assume that a non-existent location is "--", but in reality
"--" is "<space><space>". This substitution exists because mostly
because various applications have trouble digesting spaces (spaces in
the URL, for example).
The confusion begins when location is treated as empty instead, which
would imply "I want all locations" instead of "I only want locations of
<space><space>"
