[O] Bug formatting source code in new latex exporter

[Rick Frankel]

Sorry, previous mail seems to have gotten munged, lets' try again.

There is a bug with ox-latex and long listings. If the listing has a
label (name) or caption, it is wrapped in a '\begin{listing}[H]'
block. This causes listings longer than one page to be truncated if
they have labels, which means you can't have callable code longer than
one page (~40 lines for US Letter paper) and print it with minted.

The problem is on line 2178 of ox-latex:
 
  (when (or label caption)

should probably be:
       
  (when caption


An example document is below.
