**What is the current behavior?**

**If the current behavior is a bug, please provide the steps to reproduce.**
When clicking on the green arrow of a makefile recipe, a popup is shown and the folder name appears w/o the underscore it originally have (folder name was `go_bin` and the popup shows it at `gobin`)

Stop removing the underscore
