I'm missing an option variable similar to
vc-directory-exclusion-list that holds of a list of auto-generated directory names that contain temporary files that are typically but not exlusively created by build tools.
For instance the D official build tool dub creates a directory
.dub storing generated code and binary artifacts.
I could add
.dub to the
vc-directory-exclusion-list for now but I have the feeling I might run into trouble doing so.
Two named contenders of such a variable could be either
project.el could be extended with a variable similar to
but I'm not sure this feature should be restricted to projects only.
