`golangci-lint` fails because modified files exist on the same path as go.mod (flat project structure)

[shackra]

working on gitlab.com/shackra/goimapnotify, my project has a flat structure and the files I've changed exist in the root of the project, so the hook runs something like this:

golangci-lint run ./"."

which triggers a bunch of false positives:

golangci-lint............................................................Failed
- hook id: golangci-lint
- exit code: 1

if I run golangci-lint from the terminal, I get 0 issues:
