Hi

Please consider the following test org file
* A test example
,----
| #+BEGIN_SRC matlab :tangle test.m 
| function [ll x]=mitest(A0,x0)
| % initialization 
| format long
| epsi=1.e-3;
| nit=0;
| nmaxit=200;
| Delta=10;
| A=A0;
| while Delta>epsi & nit<nmaxit
|     nit=nit+1; % counter
| #+END_SRC
| Some explanation...
| #+BEGIN_SRC matlab :tangle test.m 
|     y=A*x0;
| end
| #+END_SRC
| The basic idea is.
`----


I have interrupted the while loop by some text, when I now toggle, the
indentation  is broken as you can see.

,----
| function [ll x]=mitest(A0,x0)
| % initialization 
| format long
| epsi=1.e-3;
| nit=0;
| nmaxit=200;
| Delta=10;
| A=A0;
| while Delta>epsi & nit<nmaxit
|     nit=nit+1; % counter
| 
| y=A*x0;
| end
`----

There is an empty line and
y=A*x0 is not indented.

How can this behavior be avoided?

Regards

Uwe Brauer
