+// TODO?
+// When the label specifies two values separated by a slash (curHP/maxHP,
+// curEn/maxEn, XpLevel/ExpPoints when 'showexp' is On), highlighting
+// for changes is all or nothing. curHP and curEn go up and down
+// without any change to the corresponding maximum all the time. Much
+// rarer, but when maxHP and maxEn go up with level gain, the hero
+// could be injured by a passive counterattack or collateral damage
+// from an area effect--or much simpler, the casting cost of a spell
+// that killed a monster and produced the level gain--so the current
+// value could stay the same or even go down at same time max goes up.
+// Likewise, Exp goes up a lot but Xp relatively rarely. (On the very
+// rare occasions where either goes down, they'll both do so.)
+// Highlighting two slash-separated values independently would be
+// worthwhile but with the 'single label using a style sheet for color'
+// approach it isn't going to happen.
