I think you can then simplify this to:

@@ -192,7 +192,9 @@ class Git(FetchMethod):
  
         # If the repo still doesn't exist, fallback to cloning it
         if not os.path.exists(ud.clonedir):
-            clone_cmd = "%s clone --bare --mirror %s %s" % (ud.basecmd, repourl, ud.clonedir)
+            if repourl.startswith("file://"):
+                repo = repourl[7:]
+            clone_cmd = "%s clone -l --bare --mirror %s %s" % (ud.basecmd, repo, ud.clonedir)
             if ud.proto.lower() != 'file':
                 bb.fetch2.check_network_access(d, clone_cmd)
             runfetchcmd(clone_cmd, d)
