[O] [BUG] error if arg to #+call: contains a comma

[mylesenglish]

Hello,

There may be a problem with parsing arguments to the #+call
function:

#+name: A
#+begin_src sh :var a="this, works"
echo "$a"
#+end_src

#+results: A
| this | works |

#+call: A()

#+results: A()
| this | works |

#+call: A(a="this also works")

#+results: A(a="this also works")
: this also works

#+call: A(a="this, no work")

Results in the message:

  reference 'no work"' not found in this buffer
