Running these when the ZLE is active can lead to unpredictable results.

Fix https://github.com/junegunn/fzf.vim/issues/1216

- Correct spelling/grammar

This fixes the following errors with Go 1.15:
```
src/options.go:452:69: conversion from untyped int to string yields a string of one rune, not a string of digits (did you mean fmt.Sprint(x)?)
src/options.go:463:33: conversion from untyped int to string yields a string of one rune, not a string of digits (did you mean fmt.Sprint(x)?)
```

This reverts commit e9bc7331.

The change is no longer necessary since 090dee85.

Fix #2161

- `--phony` renamed to `--disabled` for consistency
    - `--no-phony` is now `--enabled`
- Added `enable-search`, `disable-search`, and `toggle-search` actions
  for `--bind`
- Added `--color` options: `query` and `disabled`
