Also, I have few more questions (or maybe bug reports) about

1. Does org-element--current element suppose to return (paragraph ...)
   on empty buffer?

2. Some of the element parsers honour LIMIT argument partially. Part of
   the parsing is typically done using looking-at (ignoring the LIMIT)
   and part is honouring it. This can backfire when LIMIT is before
   first characteristic line of the element. For example take headline

   <point>* Example<limit> headline

   :contents-begin of the parsed headline will be _after_ :end

   Or even
   <point><limit>* example headline

   :contents-begin is  equal to :begin, sometimes leading to infinite
   loops in org-element--parse-to called by org-element-cache (hence,
   known bug with Emacs hangs when org-element-use-cache is non-nil)

   Some of the parsers potentially causing similar issues are:

   In particular, org-element-footnote-definition-parser,
   org-element-headline-parser, org-element-inlinetask-parser,
   org-element-plain-list-parser, org-element-property-drawer-parser,
   org-element-babel-call-parser, org-element-clock-parser,
   org-element-comment-parser, org-element-diary-sexp-parser,
   org-element-fixed-width-parser, org-element-horizontal-rule-parser,
   org-element-keyword-parser, org-element-node-property-parser,
   org-element-paragraph-parser, ...

 3. Some of the element parsers ignore LIMIT altogether:
    org-element-item-parser, org-element-section-parser...

    Is there any reason behind this? I though that parsing narrowed
    buffer is supposed to honour narrowing. Also, ignoring LIMIT might
    cause issue when trying to parse only visible elements.
