[bash] nnn can't return after executing command (] key) if invoked from a bind -x keybinding.

Environment details (Put x in the checkbox along with the information)

• Operating System: Ubuntu 23.10 (amd64)
• Desktop Environment: Plasma 5
• Terminal Emulator: Konsole 23.08.3
• Shell: bash 5.2.15
• Custom desktop opener (if applicable): N/A
• Program options used: none
• Configuration options set:

export NNN_COLORS='1324'
export NNN_FCOLORS='0000030A0000060805000009'

• Plugins are installed
• Issue exists on nnn master

Exact steps to reproduce the issue

1. bind -x ' "\eo":"nnn" ' (for example)
2. Press alt+o to run nnn
3. Press ] to open the command prompt
4. Run a command such as git pull
5. After command is finished, it'll get stuck and unable to return.
6. Process has to be killed by external means (kill, pkill, GUI task managers, closing the tab, etc)

Additional notes

I have nnn compiled with this script:

cd ~/Repositories/nnn
git fetch origin && git reset --hard origin/master && git clean -ffdx
make O_STATIC=1 O_NORL=1 O_EMOJI=1 strip
sudo cp ./nnn /usr/local/bin/nnn

• GCC version: gcc (Ubuntu 13.2.0-4ubuntu3) 13.2.0
• No additional patches or modifications to nnn's source.
• It does work with bind '"\eo":"nnn\n"' but this requires the prompt to be fully cleared and is added to history.

After command is finished, it'll get stuck and unable to return.

Ctrl+c worked for me.

Tried ctrl+c as one of the first things, it doesn't work for me. Neither does ctrl+z or other control keys.

This seems to be a issue with bash bind: https://stackoverflow.com/questions/16928761/why-will-a-script-not-accept-input-on-stdin-when-invoked-from-bashs-bind

Not sure if there's anything to be done on nnn's side.

Good find. Yeah seems it's not nnn's fault, better close this one.
Thanks for your assistance!
