 """ showing remotebookmarks and remotebranches in UI (EXPERIMENTAL)
 
 By default both remotebookmarks and remotebranches are turned on. Config knob to
 control the individually are as follows.
 
 Config options to tweak the default behaviour:
 
 remotenames.bookmarks
   Boolean value to enable or disable showing of remotebookmarks (default: True)
 
 remotenames.branches
   Boolean value to enable or disable showing of remotebranches (default: True)
 
 remotenames.hoistedpeer
   Name of the peer whose remotebookmarks should be hoisted into the top-level
   namespace (default: 'default')
