+This patch series replaces the text format parser used for search in\r
+Emacs with a parser for the JSON format.  This should address the\r
+escaping and flexibility problems that have plagued the text format.\r
+Like the text format, it supports incremental output.\r
+\r
+Patches 1-4 simply clean up the Emacs search code and could be pushed\r
+before the rest of the series.  Patch 5 switches to the JSON plist\r
+representation internally, but retains the text parser.  This requires\r
+some changes to the text parser to keep things working, but don't get\r
+too hung up on them since it's about to get replaced entirely.  Patch\r
+6 adds a test.\r
+\r
+Finally, patches 7 and 8 are the real meat.  Patch 7 introduces a\r
+general incremental JSON parser.  For search, we could probably get\r
+away with a simpler, hacky approach, but an incremental JSON parser is\r
+the type of thing you only want to write once---hacky or not---and it\r
+seems like the type of thing that could be useful elsewhere, too.\r
+It's general enough to support things like incremental show buffer\r
+rendering.\r
+\r
+Patch 8 rewrites the search output parser to use the JSON format via\r
+this incremental parser.\r
