Commit 4b2dfabf authored by Brion Vibber's avatar Brion Vibber

scripts/strip_geo.php to remove geodata from notices by a given user/profile.

May be slow or run out of memory if run on particularly prolific posters -- not yet optimized for that case.

Note that geodata that has already been sent out to other services (via ostatus, omb, twitter, etc) will not be removed from them.

(fixed version -- previous had accidentally undone another commit)
