Fzf should provide a way to dynamically rebind reload to change event after unbinding it

[Ultra-Code]

• I have read through the manual page (man fzf)
• I have the latest version of fzf
• I have searched through the existing issues

Info

• OS
  • Linux
  • Mac OS X
  • Windows
  • Etc.
• Shell
  • bash
  • zsh
  • fish

Problem / Steps to reproduce

RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="${*:-}"
IFS=: read -ra selected < <(
  FZF_DEFAULT_COMMAND="$RG_PREFIX $(printf %q "$INITIAL_QUERY")" \
  fzf --ansi \
      --color "hl:-1:underline,hl+:-1:underline:reverse" \
      --disabled --query "$INITIAL_QUERY" \
      --bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true " \
      --bind "ctrl-f:unbind(change)+change-prompt(2. fzf> )+enable-search+clear-query" \
      --bind "ctrl-r:unbind(ctrl-f)+change-prompt(1. ripgrep> )+disable-search+clear-query,change:reload(sleep 0.1; $RG_PREFIX {q} || true)" \
      --prompt '1. ripgrep> ' \
      --delimiter : \
      --preview 'bat --color=always {1} --highlight-line {2}' \
      --preview-window 'up,60%,border-bottom,+{2}+3/3,~3'
)
[ -n "${selected[0]}" ] && $EDITOR "${selected[0]}" "+${selected[1]}"

I have been trying to dynamically reload entries from $RG_PREFIX with the ctrl-r keybinding but to no avail after unbinding the change event from reloading with the ctrl+f binding

I can manually reload $RG_PREFIX by chaining it to the ctrl-r keybinding .ie ctrl-r:unbind(ctrl-f)+change-prompt(1. ripgrep> )+disable-search+reload(sleep 0.1; $RG_PREFIX {q} || true) but that means i will have to click ctrl-r every time the query string changes which isn't idle ,flexible or efficient like have the change event automatically do the reload for me when the query string changes

So I request that fzf provides a way to do this , I believe this is a limitation that can be overcomed.
I am by no means a guru with Go but I'm welling to learn and help anyone who will be willing to help fix this issue.

This discussion talks about this issue well maybe better than I did Dicussion on a similar issue

Wonderful tool you guys have built,Keep the great work up. 👍

Added rebind action to master branch.

#!/usr/bin/env bash

RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="${*:-}"
IFS=: read -ra selected < <(
  FZF_DEFAULT_COMMAND="$RG_PREFIX $(printf %q "$INITIAL_QUERY")" \
  fzf --ansi \
      --color "hl:-1:underline,hl+:-1:underline:reverse" \
      --disabled --query "$INITIAL_QUERY" \
      --bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true" \
      --bind "ctrl-f:unbind(change,ctrl-f)+change-prompt(2. fzf> )+enable-search+clear-query+rebind(ctrl-r)" \
      --bind "ctrl-r:unbind(ctrl-r)+change-prompt(1. ripgrep> )+disable-search+reload($RG_PREFIX {q} || true)+rebind(change,ctrl-f)" \
      --prompt '1. ripgrep> ' \
      --delimiter : \
      --preview 'bat --color=always {1} --highlight-line {2}' \
      --preview-window 'up,60%,border-bottom,+{2}+3/3,~3'
)
[ -n "${selected[0]}" ] && $EDITOR "${selected[0]}" "+${selected[1]}"

Please test it and let me know if it works as expected.

@junegunn Thanks for taking the time to work on this. The rebind action works just as it should.
