Describe the bug Executing a :read command that returns with ERRNO not equal to zero does not read stdout as it should. It just throws notice:

CommandLine: Error executing cmd=r! ./bin/pob. err=Error: Command failed: ./bin/pob .

To Reproduce

1. Make a binary printing to stdout and then returning a not zero result. Dart example tested:

// > pob.dart; dart compile exe -o bin/pob bin/pob.dart

import 'dart:io';

void main() {
  print('Stdout NOT taken!');
  exit(33);
}

2. do :r! ./bin/pob
3. See error "CommandLine: Error executing cmd=r! ./bin/pob. err=Error: Command failed: ./bin/pob" notice .

Expected behavior Output of command should be read into the buffer. Regardless of process returning non-zero. This is a normal behavior of scripts that are meant for both in pipe and interactive work.

Workaround Pipe for region behaves. You can read output with :adr,adr! where adr is set at existing empty line. So as a workaround just use :7,7! command instead of :r! in 7 line.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.23.1
• VSCode version: 1.69.1
• OS: macOS 12.3

Additional context

"terminal.integrated.shellIntegration.enabled": false but settings UI says "Enabled".

I also experienced an editor keyboard input hang (with cmdline hanging) with above reported :read command outputs bug. Output was in range of a few kB. Just notice here for posteriority, as I have no time to make a reproduction case; then this hang is likely an effect of command stdout not being properly disposed.

Edit: hanging vim cmdline confirmed with way less output.
