+``storage``
 ----------
 
 Control the strategy Mercurial uses internally to store history. Options in this
 category impact performance and repository size.
 
-``optimize-delta-parent-choice``
+``revlog.optimize-delta-parent-choice``

     a possible delta base. This results in better delta selection and improved
     revlog compression. This option is enabled by default.
