commit f7d6db1bf6c479fa537f198c791851e248e5cdb1

    org-bibtex-read: Do not add nil when there is no entry at point
    
    * lisp/ol-bibtex.el (org-bibtex-read): Previously, when there is no
    entry at point, `nil' would be added to `org-bibtex-entries' causing
    errors later, i.e. upon calling org-bibtex-write.  Now, nil is never
    pushed to `org-bibtex-entries'.
