+Previously, we cleaned the downloaded performance corpus and the\r
+cached indexes on 'make clean'. This seems heavy-handed, since these\r
+take a long time to download, unpack, and index. They also aren't\r
+make targets to begin with. Move cleaning these to 'make distclean'.\r
+This isn't exactly the right meaning of "distclean", but it's closer.\r
