+Modify the "Edit on Github" links to handle auto-generated pages in the
+example gallery and the API reference listings.  The GH links that sphinx
+generates by default make the assumption that an HTML file comes from an RST
+file with the same filepath, which isn't the case for autogenerated files. The
+logic to generate the correct URL is in conf.py, but we still have to modify
+the template here to change the "Edit this page" text to "View on GitHub".
