Hi all,

I believe this change is breaking the ox-twbs package.

The error shown is:

newline)))
  eval-buffer()  ; Reading at buffer position 5862


The error goes away after I comment out the line with :export-block keyword
in the org-export-define-backend function call.

Example:
https://github.com/marsmining/ox-twbs/blob/cfe67353d148e65a7676f1609d8cc22a4c8fbc78/ox-twbs.el#L108

What would be the proposed/correct fix for this?

Thanks.
