* Don't do shell quoting for weird chars

This would prevent tabs from being escaped as `$'\t'` (definitely not what I would want to see as initial value in the search).

* Do different escape.

This reverts commit 3a6af275.

CTRL-R binding used to start with --no-sort to list the matched commands
in chronological order. However, it has been a constant source of
confusion. Let's enable it by default from now on. The sorted result
shouldn't be too confusing as we use --tiebreak=index.

This removes the need for the 'sed' call. Faster, cleaner.

`-fstype dev` is invalid. It's devfs on macOS and devtmpfs on Linux.

zle automatically calls zle-line-init when it starts to read a new line. Many
Zsh setups use this hook to set the terminal into application mode, since this
will then allow defining keybinds based on the $terminfo variable (the escape
codes in said variable are only valid in application mode).

However, fzf resets the terminal into raw mode, rendering $terminfo values
invalid once the widget has finished. Accordingly, keyboard bindings defined
via $terminfo won’t work anymore.

This fixes the issue by calling zle-line-init when widgets finish. Care is taken
to not call this widget when it is undefined.

Fixes #279

This allows to have a custom widget like the following, which would
additionally accept the line, but only in case of entries being
selected:

    fzf-file-widget-with-accept() {
      zle fzf-file-widget
      if [[ "$?" == 0 ]] && (( $#BUFFER )); then
        zle accept-line
      fi
    }
    zle     -N   fzf-file-widget-with-accept
    bindkey '\e^T' fzf-file-widget-with-accept

With this `<C-a>t` will launch fzf, and simulate the pressing of "Enter"
afterwards.

In the case that fzf-tmux returns a user-selected result but with a
non-zero exit status (which can happen if a function inside $PS1 returns
non-zero) this allows CTRL-R to continue working as expected.

Addresses #203 (Tranquility's comment)

Fixes #363.

Close #40

Since we now use fzf-tmux instead of tmux split-window

In addition to being simpler, it allows subsequent up/down history
or accept-line-and-down-history widgets to work.
Also allow for find being and alias if alias expansion
after command is enabled.

at least my version of head wants -n1 to only display the first line

Note that CTRL-T on bash is still using the old trick of send-keys.
