OK - here it is:

| :BABEL:
| #+PROPERTY: exports code
| #+PROPERTY: comments yes
| #+PROPERTY: padline yes
| :END:
| * newASM (./newASM.R)
| :PROPERTIES:

|     logList("#### be initialised for usage when simulated by running")
|     logList("####")

|     logList("####")
|     logList("#### or manually, without simulating, by running")
|     logList("#### > ASM <- initialize(ASM)")
|     logList("####")
|     
logList("##########################################################################")

|     
logList("##########################################################################")
|     logEnd()
|     return(ASM)
|   }
| #+end_src
`----

where the tangled file looks as follow, including the empty lines at
beginning and end:

,----
| 
| ## [[file:~/tmp/jumpBack.org::*newASM%20(./newASM.R)][newASM\ 
\(\./newASM\.R\):1]]
| 
| 
logList("##########################################################################")
|   
logList("##########################################################################")
|   logList("####")
|   logList("#### Simulation object ASM created.")
|   logList("####")
|   logList("#### It has been undergone basic initialisation and will")
|   logList("#### be initialised for usage when simulated by running")
|   logList("####")
|   logList("#### > sim(ASM)")
|   logList("####")
|   logList("#### or manually, without simulating, by running")
|   logList("#### > ASM <- initialize(ASM)")
|   logList("####")
|   
logList("##########################################################################")
|   logList("####")
|   logList( paste("#### GISDBASE : ", parms(ASM)$baseDir) )
|   logList( paste("#### LOCATION : ", parms(ASM)$grassLocation) )
|   logList( paste("#### MAPSET   : ", parms(ASM)$grassMapset) )
|   logList("####")
|   
logList("##########################################################################")
|   
logList("##########################################################################")
|   logEnd()
|   return(ASM)
| }
| 
| ## newASM\ \(\./newASM\.R\):1 ends here

This one works, although the cursor is consistently two characters to the left 
then
where it should be.

If I change

,----
| #+PROPERTY: padline yes
`----

to

,----
| #+PROPERTY: padline no
`----

the padlines are gone, ant the jumping back is completely off (from
first r in return() it jumps to the third # in the last logList()).

Hope this helps,

Rainer
