Not sure why we wouldn't want to treat $(cat food) as a single token?
Do you mean, as opposed to ${cat_food}?  IIUC, I'd like both $() and ${}
to be skipped over for the purposes of indentation:

#+begin_src sh
${top_dir}/foo --bar \
               --baz

$(git rev-parse --show-toplevel)/foo --bar \
                                     --baz
#+end_src

Gotcha.
