OK, sorry for spamming the list with idiot questions. I see why the 
above fails for functions. The command

"ess-eval-function-or-paragraph-and-step"


behaves differently when it is run within a function and when it is run 
on a paragraph - in the latter case it leaves the cursor two lines below 
the paragraph, and in the former case just one line.

My cobbled together function assumes that it will always leave two 
lines. Now I can patch the ess-eval function, or tweak my function, but 
I would rather be able to 'do it right'. How do I get the effect of 
ess-eval-line-and-step without running ess-eval-line-and-step? I.e. show 
the process window and move to the bottom?
