[PATCH] Continue numbering from any previous numbered snippet with +n, even when previous numbered snippet does not immediately precede it.

[Niels Giesen <niels.giesen@gmail.com>]

* org-mode/lisp/org-exp.el (org-export-number-lines):

  Check whether number parameter (this is a numbered block!) is
  non-nil as well as whether cont is nil (this numbered block should
  *not* continue numbering where we left off before!) before resetting
  the count to zero.

  From the docs:

    If you use a `+n' switch, the numbering from the previous
    numbered snippet will be continued in the current one.

  With this change I believe the code complies with the docs.
