+"""Combine similar index entries into an entry and subentries.
+
+For example:
+
+    \item {foobar} (in module flotz), 23
+    \item {foobar} (in module whackit), 4323
+
+becomes
+
+    \item {foobar}
+      \subitem in module flotz, 23
+      \subitem in module whackit, 4323
+
+Note that an item which matches the format of a collapsable item but which
+isn't part of a group of similar items is not modified.
