Hello again list,

Just for completeness I want to post my solution to the below issue. It
turned out the behaviour was caused by the variable
org-src-tab-acts-natively. When set this seems to activate reading the
header arguments when tabbing in the src block.

My solution now is to move the evaluation to a call statement:
    #+name: do-stuff
    #+begin_src sh
        echo $USER
    #+end_src

    #+CALL: do-stuff[:dir (concat "/ssh:" (read-string "login name: ")
"@some.other.place:/scratch")]

Regards
Andreas
