    Make org-open-at-point only ask once whether new header should be created.
    
    When following "thisfile" links org-open-at-point is kind enough to
    retry org-link-search again after widening the buffer it can't be
    found. However org-link-search also asks the question "No match -
    create this as a new heading? (y or n)" when target can't be
    found. This means that the question is asked twice when following a
    nonexistent link and answering no.
    
    This is fixed by setting org-link-search-inhibit-query in first try,
    so only second invocation asks the question.
