ascii-export vs. "<<" and ">>" patch

ascii-export vs. "<<" and ">>" patch

[-- Attachment #1: Type: text/plain, Size: 657 bytes --]

Hi.  I'm using org-mode to write some documentation about Erlang
modules.  Erlang's "binary" data type has a syntax like:

   <<"this is binary data">>

Org-mode's ascii-exporter in version 6.33f blindly strips all <<>>
pairs from the file, leaving the text as

   "this is binary data"

which, unfortunately, is still valid Erlang syntax, but has a different meaning.

So, to help me and others write Erlang documentation in org-mode, I
submit the patch attached to this email, which changes org-ascii.el
such that it checks the org-protected text property before stripping
<<>> characters, so examples marked as verbatim text should go
untouched.

First of all, you should have such code in code blocks like # 
+begin_src..., or, in running text, you need to protect it with  
something like =<<"this is binary data">>=.

Then things will work in HTML.

There is indeed a bug in ASCII export which does remove these without  
checking for protection - but I have just fixed that - so if you pull  
and protect, things should work.
