Agreed - delete the one that has the wrong spelling. We should probably try
to feed this info back to USGS (http://geonames.usgs.gov/) somehow.

Sure it can :) key=value1;value2;value3... is the correct way to add
multiple values for a key.

In this case, it looks like there is one node for the whole museum and
another for the specific gallery. I'd delete the third one, place the first
in the middle of the whole museum (or on a closed way surrounding it), and
the second in the approximate position of that gallery.
