Re: Bug: C-c ' eats last newline of a figure [6.35trans (release_6.35g.72.g2e12)]

[Dan Davison <davison@stats.ox.ac.uk>]

I've had a quick look at this. A minimal example is

#+begin_src ditaa
  +--
#+end_src

The problem seems to be that C-c ' concludes that we're in a table.el
table. One solution that came to mind is to move the test for table.el
context until after all the other block regexps have been tried. Patch
below.

    Don't jump to conclusion that we are at table.el table
    
    Test various block regexps before testing for table.el context
