[Orgmode] Bug: table parsing is on in BEGIN_EXAMPLE section

[Wanrong Lin]

Hi,

I just had a need to use the +BEGIN_EXAMPLE marker, and I found that if 
I have a directory tree listing like this:

+BEGIN_EXAMPLE
    +---bin
    |   +---decoder_a.exe
    |   +---decoder_b.exe
    |   +---encoder.exe
    +---doc
+END_EXAMPLE


It will be treated (and font-locked) as a table. Not really a a big deal 
unless I press the "Tab" key on it. Just want to report it in the hope 
that it is a snap for Carsten to fix it. :-)
