[MapServer-users] Mapfile -> EMPTY-Parameter -> Migrate from MS 7.6 -> 8.0

[Steve Lime]

Hi Georg: There was a regression in 8.0 that broke the EMPTY redirection.
It had to do with considering 0 results as a valid query result and not an
error. The functionality was fixed in 8.2 and is working fine for me at
least.
