MarsSeed [1] filed a deletion request for sixel-tmux-git [2]: Abandoned, broken fork of tmux from 3 years ago. [a]
Also unneeded: upstream tmux now has built-in sixel support. Arch/extra/tmux already enables it during the build. [a]: https://github.com/csdvrx/sixel-tmux [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/sixel-tmux-git/
