Dynamically select which __fzf_select__ to use for tmux with bash 4+.

Browse Source 
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.
