+1.0b (5 November 2010)
+
+- work around platform-specific Vim 7.3 bug seen by some users (wherein
+  Vim always falsely reports to Ruby that the buffer numbers is 0)
+- re-use the buffer that is used to show the match listing, rather than
+  throwing it away and recreating it each time Command-T is shown; this
+  stops the buffer numbers from creeping up needlessly
+
