+:mod:`readline`: Explicitly disable bracketed paste in the interactive
+interpreter, even if it's set in the inputrc, is enabled by default (eg GNU
+Readline 8.1), or a user calls ``readline.read_init_file()``. The Python REPL
+has not implemented bracketed paste support. Also, bracketed mode writes the
+``"\x1b[?2004h"`` escape sequence into stdout which causes test failures in
+applications that don't support it. It can still be explicitly enabled by
+calling ``readline.parse_and_bind("set enable-bracketed-paste on")``. Patch by
+Dustin Rodrigues.
