To help keep things organized, the change that @horosgrisa applied and asked @psprint to check is 1194d15.

I would like to add that although I don't fully understand the code I commented out these lines to solve another problem I encountered. I'm using terminator, and the following cuase the shell prompt to stop working propetly (no color, no git integration etc.):

1. Enter a folder with .env file.
2. Split the terminator window into two (pwd in the new window will point to the same location, but the environment won't be activated, which is fine).
3. In the new window, activate the environment with source .env.
4. Exit the directory.

It may be related to the original issue, or not. In any case, it can indicate that there is an issue with this part of the plugin.
