Our git version is v2+ for some time now, but go.mod
still declared v1. Hopefully making both match makes
https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work.
All the import paths have been fixed like this:
find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%
Issues were:
# github.com/rfjakob/gocryptfs/contrib/findholes/holes
contrib/findholes/holes/holes.go:136:2: unreachable code
# github.com/rfjakob/gocryptfs/tests/root_test_test
tests/root_test/root_test.go:139:2: unreachable code
Also make sure we actually run "go vet" against the whole
codebase.
