+ Improved w-differences diagram generation with included "absolute"
+ values.
+
+	* src/main/java/de/intevation/flys/exports/WDifferencesCurveGenerator.java:
+	  Fixed one (of two) incorrect labels.
+	  (doWaterlevelOut): Survive non-found gauge, fetch kilometer and w
+	  instead of values for w and q.
