" From ECMA-48:
"
"   OSC - OPERATING SYSTEM COMMAND:
"     Representation: 09/13 or ESC 05/13 (this is \033] here)
"     OSC is used as the opening delimiter of a control string for
"     operating system use.  The command string following may consist
"     of a sequence of bit combinations in the range 00/08 to 00/13 and
"     02/00 to 07/14.  The control string is closed by the terminating
"     delimiter STRING TERMINATOR (ST).  The interpretation of the
"     command string depends on the relevant operating system.
"
" From man screen:
"
"   Virtual Terminal -> Control Sequences:
"     ESC P  (A)  Device Control String
"                 Outputs a string directly to the host
"                 terminal without interpretation.
"     ESC \  (A)  String Terminator
"
" From tmux OpenBSD patchset 866:
"
"   Support passing through escape sequences to the underlying terminal
"   by using DCS with a "tmux;" prefix. Escape characters in the
"   sequences must be doubled. For example:
"
"   $ printf '\033Ptmux;\033\033]12;red\007\033\\'
"
"   Will pass \033]12;red\007 to the terminal (and change the cursor
"   colour in xterm). From Kevin Goodsell.
"
" From tmux OpenBSD patchsets 915 and 916:
"
"   Support xterm(1) cursor colour change sequences through terminfo(5) Cc
"   (set) and Cr (reset) extensions. Originally by Sean Estabrooks, tweaked
"   by me and Ailin Nemui.
"
"   Support DECSCUSR sequence to set the cursor style with two new
"   terminfo(5) extensions, Cs and Csr. Written by Ailin Nemui.
"
"   NOTE: The following commit appears to break this feature.
"
"   commit 13441e8cb8b0ce68db3204a44bbdc004bee42a0f
"   Author: Nicholas Marriott <nicm@openbsd.org>
"   Date:   4 months ago
"
"       The actual terminfo entries we ended up with for cursor changes are Cs,
"       Ce, Ss and Se (not Cc, Ce, Cs, Csr). So use and document these instead
"       of the ones we were using earlier.
"
" From :help t_SI:
"
"   Added by Vim (there are no standard codes for these):
"     t_SI start insert mode (bar cursor shape)
"     t_EI end insert mode (block cursor shape)
