handlePackageDetailsRedirect redirects all redirects to "/pkg" to "/".

func (s *Server) handlePackageDetailsRedirect(w http.ResponseWriter, r *http.Request) {

handleModuleDetailsRedirect redirects all redirects to "/mod" to "/".

stdlibPathForShortcut returns a path in the stdlib that shortcut should redirect to, or the empty string if there is no such path.

func stdlibPathForShortcut(ctx context.Context, db *postgres.DB, shortcut string) (path string, err error) {
	defer derrors.Wrap(&err, "stdlibPathForShortcut(ctx, %q)", shortcut)
	if !stdlib.Contains(shortcut) {
		return "", nil
	}
	matches, err := db.GetStdlibPathsWithSuffix(ctx, shortcut)
	if err != nil {
		return "", err
	}
	if len(matches) == 1 {
		return matches[0], nil

No matches, or ambiguous.
