Hi

Some fixes to inline src block execution via org-ctrl-c-ctrl-c
where point is beyond white-space in the inline src block body...

* Start Pomodoro
 #src_emacs-lisp[:results silent]{( org-timer-set-timer 25 )} 
                         ^
,------------------------'
| C-c C-c execution
| was broken beyond 
| here
`------------------

Also fixes to inline src block execution where the inline src block 
happens to be on the first line of a buffer. 

I've included tests and test data.

Regards

Martyn

Subject: [PATCH] Bug fixes to inline source block execution triggering.
 * lisp/ob.el: Created org-babel-get-inline-src-block-matches() to fix
 problems with org-ctrl-c-ctrl-c not triggering inline src block
 execution when point is on or after a space within the inline src
 block body. Also fixed execution problems where inline src block is on
 buffer line 1.
 * testing/examples/babel.org: Test data for
 org-babel-get-inline-src-block-matches()

* testing/lisp/test-ob.el: Tests for
  org-babel-get-inline-src-block-matches()
