このコミット以降、boron にて以下のようにテストに失敗しています。
+ <n>) Failure:
+test_modify_text_in_pre_input_hook(TestReadline) [/extdisk/chkbuild/chkbuild/tmp/build/<buildtime>/ruby/test/readline/test_readline.rb:386]:

boron (Debian squeeze 6.0.4) は Readline 4.3 を使っているのですが、これだと
naruse@boron:~/ruby$ ./ruby -rreadline -e'Readline.input=open("version.h");Readline.readline("> ")'

のようにエコーバックされず、6.1 とかだと、
% ./ruby -rreadline -e'Readline.input=open("/home/naruse/ruby/version.h");Readline.readline("> ")'
> #define RUBY_VERSION "2.0.0"
と、入力が表示されるようです。

拡張ライブラリ readline で補完時の処理をカスタマイズするため rl_pre_input_hook, rl_insert_text, rl_redisplay をサポートして欲しいです。
叩き台としてパッチを添付します。
