[PATCH] Fix table variable with commas in ob-sqlite

[Eduardo Bellani <ebellani@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 3566 bytes --]


ob-sqlite.el: Enable table with fields containing commas to be used as
arguments to sqlite source blocks

* lisp/ob-sqlite.el: Stop interfering with the 'orgtbl-to-csv' default
  formatting.

* testing/lisp/test-ob-sqlite.el:: Adds a test using a table with
  commas in the content of any of its fields as an argument for a
  sqlite source block. Use the 'org-test-with-temp-text' pattern.


The problem here was that ob-sqlite was providing a format to the
'orgtbl-to-csv' that actually overwrote the default format in that
function, and in the case where there were commas in the content of the
table, broke the table as argument mechanism.
