+Subject: Patch 7.2.400
+Fcc: outbox
+From: Bram Moolenaar <Bram@moolenaar.net>
+Mime-Version: 1.0

+Patch 7.2.400 (after 7.2.387)
+Problem: Dynamic Ruby is not initialised properly for version 1.9.1.
+ Ruby cannot create strings from NULL.
+Solution: Cleanup #ifdefs. Handle NULL like an empty string. Add
+ ruby_init_stack. (Sergey Khorev)
