+/* Explanation
+
+The XML indenter simply inherits the indentation of the previous line,
+with the first line starting at 0 (of course!). For each element that
+is opened on the previous line, the indentation is increased by one
+level; for each element that is closed, it is decreased by one.
+
+We also have a special case of opening an element on one line and then
+entering attributes on the following lines, in which case we would like
+to see the following layout:
+<elem attr="..."
+      blah="..." />
+
+<x><a href="..."
+      title="..." />
+</x>
+
+This is accomplished by checking for lines that contain an unclosed open
+tag.
