virtualenv-init break mc (Midnight Commander) subshell

[fizista]

When this plugin is running, the midnight commander shell does not work when you press CTRL+O.

Steps needed to repeat the problem:

1. Create file .bash_test_rc

   export PYENV_ROOT="$HOME/.pyenv"
   command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"
   eval "$(pyenv init -)"
   eval "$(pyenv virtualenv-init -)"

2. Run bash --rcfile ~/.bash_test_rc --verbose

3. Run mc

4. Press CTRL+O

5. The bash shell should appear, but unfortunately it does not appear.
