* 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 376a76d1 as it
affects normal completion

This also modifies <C-t> behaviour.
The longest file path in the input is used as root directory for `find`
command. The remainder of the input is passed to fzf's --query as a
initial search parameters.

closes #440

If "." is given as the argument to begin <C-t> completion, the leading
"." is not correctly removed. In general, if user selects a fzf
completion, the current token should be "consumed".

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.

Ref #790

Close #799

Close #791

_fzf_completion_loaded is no longer checked. This change increases the
load time by a few milliseconds, but I can't think of a better way to
handle the issue.

Close #783.

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

Replace the "temp file" workaround with the "read" function: it's
simpler and faster.

Use proper escaping, remove the custom function.

The "file" widget uses last token as root for the "find" command.
This replaces the equivalent of '**' completion in bash/zsh.
The "$dir" non-expanded variable can be used in FZF_CTRL_T_COMMAND to
set the root.

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

It doesn't short circuit like we expect, causing trouble when $dir is
empty

Use shell builtin instead

Handle uppercase letters in program names. This also deals with `-` and
`.`, both of which are quite common in program names, e.g., `xdg-open`
and `foo.sh`.

The command substitution and following word splitting to determine the default
zle widget for ^I formerly only works if the IFS parameter contains a space. Now
it specifically splits at spaces, regardless of IFS.
