Bugfix: FSS Extended Write is not properly quoting quotes.

When writing using a quote character that is not the selected quote to use when writing, these other quote character must still be quoted.
Take for example this:
  # fss_extended_write -oc "'" '"' -oc '"' "'" -oc ' `' "\` " -oc "'" "'"
  "'" "\""
  "\"" "'"
  "`" "` "
  "'" "'"

Quoting the quotes is necessary to ensure that the FSS Extended Read properly works.
Otherwise the [' '] would be read as an Object without Content when instead the code should be ["'" "'"] which would be read as an Object of ' and a Content of '.
