in the latest source (current tip of our main development branch) there is the method

   Node.FS.Dir.rentry_exists_on_disk(name)

for exactly this purpose. It returns True if the given file exists locally, or in one of the repositories (remote locations). You 
can then create a proper Node for it, and use get_contents().
