-Subject: [PATCH 1/2] Recognize Meta+Left and Meta+Right
-
-Recognize `Alt-Left` and `Alt-Right` for navigating by words in more
-terminals/shells/platforms.
-
-I'm not sure exactly where to find canonical documentation for these
-codes, but this seems to match what my terminal produces (macOS + iTerm2
-+ Fish + Tmux).
-
-It might also be nice to have some more support for editing the bindings
-for these characters; sequences of more than one character are not
-supported by `el_bind_key` and similar.
-
-Originally from: https://github.com/troglobit/editline/pull/70
-This patch is applied upstream: https://gerrit.lix.systems/c/lix/+/1883
