Subject: [PATCH] Patch from Matsui Nag to implement xterm's "bracketed paste
 mode", in which text pasted into the terminal is preceded
 and followed by special function-key-like escape sequences
 ESC[200~ and ESC[201~ so that the application can identify
 it and treat it specially (e.g. disabling
 auto-indent-same-as-previous-line in text editors). Enabled
 and disabled by ESC[?2004h and ESC[?2004l, and of course
 off by default.
