[Orgmode] Emphasis spanning more than two lines doesn't get font-lock'ed

[Sebastien Delafond]

This is a follow-up to Debian bug #569752[1], which states that with the
following org snippet :

  foo *foo* foo
  foo foo *foo
  foo* foo foo
  foo foo *foo
  foo foo foo
  foo* foo foo

you only get 2 spans of text highlighted by font-lock as "bold", instead
of 3 (the 3rd one, spanning more than 2 lines, isn't recognized); seeing
how exporting this same snippet through org does indeed show 3
emphasized spans, should this be considered a bug ?

Cheers,
