[ELPA Syncer]

branch: externals/denote
commit 92e15886d51925711b64042b772078809d4828d6

    Avoid errors with string value for keywords
    
    This is done in order not to break user-level custom code, such as what
    we had in the manual:
    
        (defun prot/denote-journal ()
          "Create an entry tagged 'journal', while prompting for a title."
          (interactive)
          (denote
           (denote--title-prompt)
           "journal"))
