Subject: [PATCH] UI-Coordinates: fix insidious bug

util::contains used to pick the overload for strings,
i.e. it first converted the UI-Coordinates to diagnostic output format
and then searched that string for '*' to determine if the pattern is explicit

works as expected, but not what you'd intend....
...and breaks spectacularly once you search for something as innocuous as '.'
