Thanks for the confirmation, that there is no possibility to expand a
#+call line.

I know, that I can jump to the code block and expand that one (quite
fast with C-c C-v g RET C-c C-v v), but that is exactly *not* what I was
looking for.  Because then, the header arguments to the source code
block will apply instead of the header arguments to the #+call line.

I was hoping for a C-c C-v v on #+call lines, which would spare me from
modifying the source block's header arguments.  But it is not a pressing
issue, just my laziness (and bad coding perhaps).
