yes, the Worg documentation is in dire need of maintenance, see below
for discussion of how arguments are passed in the sh blocks

here scripts are how Babel sends data through to a shell script, as far
as I know they should have no issues with quotes (or any other
character)
specifically, the following code block
#+results: something
#+begin_example
something
and something else
with apostrophes ' and quotes "
this should all work...
#+end_example
#+begin_src sh :var data=something
echo $data
#+end_src
Expands to
#+begin_src sh
data=$(cat <<BABEL_STRING
something
and something else
with apostrophes ' and quotes "
this should all work...
BABEL_STRING
)
echo $data
#+end_src
