[O] Stable 9.1.3 demands explicit empty string in (file) as capture target

[Umbromancer]

Hi,

This may be intended, but before it was possible (and there is a lot
of code and examples in the wild) to have a capture template element
such as:

(setq org-default-notes-file "~/Documents/orgfiles/inbox.org")

  (setq org-capture-templates
        '(("t" "Todo" entry (file)
           "* TODO %^{Brief description} %^g\n %u\n %?" :empty-lines 1)
   ...))


While with stable 9.1.3 an empty string must be explicitly passed in
(file "") if org-default-notes-file is to be used as the target.
