Issue

• When attempting to use tab-completion in a project dir that uses direnv via a .envrc file, vf activate causes direnv to load and unload the directory which leads to cluttered output (the correct line with completion shows up after the loading and unloading of direnv stuff.
• I'm guessing that internally, there is some sort of directory changing that happens which triggers this, so I am not sure if this is actually something that can be fixed.
