Archiving always adds a newline before entries

[John Wiegley]

I like to avoid blank lines between Org-mode entries, but have found that when
archiving (and not use datetrees), that this is not supported by Org-mode
out-of-the-box. Mainly it’s due to these lines:

      (if (and heading (not (and datetree-date (not datetree-subheading-p))))
          …
        ;; No specific heading, just go to end of file, or to the
        ;; beginning, depending on `org-archive-reversed-order'.
        (if org-archive-reversed-order
            …
          (goto-char (point-max))
          ;; Subtree narrowing can let the buffer end on
          ;; a headline.  `org-paste-subtree' then deletes it.
          ;; To prevent this, make sure visible part of buffer
          ;; always terminates on a new line, while limiting
          ;; number of blank lines in a date tree.
--->      (unless (and datetree-date (bolp)) (insert "\n"))))
      ;; Paste
      (org-paste-subtree (org-get-valid-level level (and heading 1)))

The line indicated above always appends a newline at the end of the buffer,
so that the pasted tree appears after this newline. It would be nice if this
followed the configuration of ‘org-blank-before-new-entry’, for example.

Meanwhile, I corrected the behavior with advice. Not ideal, since it affects
all cases of pasting subtrees, but it works well enough:

  (advice-add 'org-paste-subtree :before #'(lambda (_) (delete-blank-lines)))
