+\r
+That would require the user to conditional build with:\r
+\r
+#if NOTMUCH_CHECK_VERSION(0, 17, 90)\r
+ /* building against post-0.17 git master or released 0.18 */\r
+#else\r
+ /* building against 0.17 */\r
+#endif\r
+\r
+instead of the IMHO more natural and accurate:\r
+\r
+#if NOTMUCH_CHECK_VERSION(0, 18, 0)\r
+ /* building against post-0.17 git master or released 0.18 */\r
+#else\r
+ /* building against 0.17 */\r
+#endif\r
