Also remove blank lines before the ";;; org*el ends here" declarations.
Having a "Version" header forced us to update every file when releasing a
new version of Org; it also forced us to update every file when merging Org
with Emacs trunk, thus cluttering the diffs between the previously merged
version and the new one with useless information.

Hi,
When evaluating shell code blocks in org-babel, the execution seems to hang
indefinitely. The following patch is trying to fix this problem by modifying
the way shell code is send to comint and the way the end-of-evaluation
indicator is looking for.
As I am far from an emacs lisp expert and as the patch modifies the widely use
org-babel-comint-with-output function, it certainly needs some testing. I've
made some tests with shell and R code blocks, but I'm not sure it's enough.
Thanks !

Fix sh block execution in a session
* lisp/ob-sh.el (org-babel-sh-evaluate) : when sending input to comint, wait
until previous line execution is finished
* lisp/ob-comint.el (org-babel-comint-with-output) : when looking for
end-of-evaluation indicator, search forward for the indicator before searching
forward for the prompt
* ob-comint.el (org-babel-comint-eval-invisibly-and-wait-for-file): New
function to evaluate code invisibly and block until output file exists.
* ob-R.el (org-babel-R-evaluate-session): Use
`ess-eval-buffer' to evaluate R code in session for :results
value. Write result to file invisibly using new function
`org-babel-comint-eval-invisibly-and-wait-for-file'.
These changes move to using standard ESS code evaluation in R sessions
in the :results value case, which avoids unnecessary output to the
comint buffer. In addition, the R command responsible for writing the
result to file is hidden from the user.
For some reason ob-R refuses to compile when it requires ob-comint.
When (require 'ob-comint) is not included in ob-R.el everything
compiles without error, but warnings are thrown because the
arguments to a macro defined in ob-comint are mis-interpreted as
functions.
When (require 'ob-comint) is added to ob-R.el then it throws errors
complaining that the last argument to a function is nil and should
be a string. I don't understand this error at all and can't fix it.
