Hi,

I've just noticed that I get an infinite loop when importing csv tables
into Org-mode tables.  For example calling 

  (org-table-convert-region (point-min) (point-max) '(4))

from inside of a simple text file containing the following

--8<---------------cut here---------------start------------->8---
1,2,3
1
2
3
5
--8<---------------cut here---------------end--------------->8---

results in an infinite loop.  The attached patch fixes this issue [1],
however it seems weird that this would just surface now, given that the
code in question has been in the repo since last fall

|     Correctly interpret CVS tables with quoted fields
|     
|     The csv parser was very primitive, ignoring quoted fields.  This is
|     now fixed.

Has anyone else noticed this problem? Should I go ahead and apply this
patch?

Subject: [PATCH] org-table: fix infinite loop in table importation

* lisp/org-table.el (org-table-convert-region): don't continue csv
  importation which the point catches the end, this fixes an infinite
  loop which was caused by the (point) never catching up with the
  "end" marker
