Bug: Babel blocks with continuation line at end of block fails to export [7.8.03 (release_7.8.03.542.gdfeac)]

Hi Eric,

I ran into a Babel related export problem at work where I took 
a single C source line in a block which has a trailing \ for a
continuation character like the following example.

,----[ test.org ]
| * Text export
| #+begin_src c
|   #define FOO bar \
| #+end_src
`----

If I try to export this file I get a "Beginning of buffer" error and
the export fails.  I can fix it by removing the trailing \ or adding
another line to the end of the block.

This took a while to find in my huge work org file by manually selecting
headings to export until I found the problem block.  I think babel
should probably handle this more gracefully (if possible) and just 
ignore the error and continue.

Thanks for all your great work!!

Regards,
Bernt

Hi Bernt,

This is a problem with the HTML exporter (notice that export to ASCII
works as expected).  I can reproduce the problem, but I'm not very
familiar with the workings of the exporters, so I can't suggest or
implement a fix.

Best,

Fair enough.  Maybe this will get addressed when the new exporter is
built.

Thanks for looking at it.

Unfortunately, not at the moment.

AFAICS, the problem seems to come from (font-lock-fontify-buffer) call
in `org-e-html-format-source-code-or-example-colored' function.
