Chaoren Lin 54b4b0c56f Dynamically select which __fzf_select__ to use for tmux with bash 4+.
Instead of choosing one at initialization, choose the correct one
when it's actually called, so that the behavior is correct even after
resizing.

Bonus fixes for tmux with bash 4+:
- No extra space when cancelling CTRL-T.
- Fix cursor position problem in vi mode.
