Make sure user-properties remain user-properties.

This is a partial merge of Ant.java from the 1.5 branch (only partial,
sorry Magesh) that is required to avoid a Gump build failure of

inheritall values and ends up with relying on a property that has been
set on the command line but has disappeared).
