    # Support for "bracketed paste"
    # The way it works is that we acknowledge our support by printing
    # \e\[?2004h
    # then the terminal will "bracket" every paste in
    # \e\[200~ and \e\[201~
    # Every character in between those two will be part of the paste and should not cause a binding to execute (like \n executing commands).
    #
    # We enable it after every command and disable it before (in __fish_config_interactive.fish)
    #
    # Support for this seems to be ubiquitous - emacs enables it unconditionally (!) since 25.1 (though it only supports it since then,
    # it seems to be the last term to gain support).
    # TODO: Should we disable this in older emacsen?
    #
    # NOTE: This is more of a "security" measure than a proper feature.
    # The better way to paste remains the `fish_clipboard_paste` function (bound to \cv by default).
    # We don't disable highlighting here, so it will be redone after every character (which can be slow),
    # and it doesn't handle "paste-stop" sequences in the paste (which the terminal needs to strip, but KDE konsole doesn't).
    #
    # See http://thejh.net/misc/website-terminal-copy-paste. The second case will not be caught in KDE konsole.
    # Bind the starting sequence in every bind mode, even user-defined ones.

    # We usually just pass the text through as-is to facilitate pasting code,
    # but when the current token contains an unbalanced single-quote (`'`),
    # we escape all single-quotes and backslashes, effectively turning the paste
    # into one literal token, to facilitate pasting non-code (e.g. markdown or git commitishes)
