Fabian Homborg eb35975c0f Make cancel-commandline actual bind function
This was always awkward as fish script, and had problems with
interrupting the autoloading.

Note that we still leave the old function intact to facilitate easier
upgrading for now.

Fixes #7145.

# 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).
#
# 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).
#
# See http://thejh.net/misc/website-terminal-copy-paste.
