    Add a work-around for completing topics in the info dir
    
    * ivy.el (ivy-read): Weirdly, the topic names need to be wrapped in
      "(...)". Also, `all-completions' returns nothing for "", but returns
      stuff for "(". Also, `all-completions' for "(" returns plenty of
      duplicates.
