Hello, I have a problem when using `vcount' in table.

As the following table:

#+BEGIN_SRC
|   |       date |
|---+------------|
| * | 2014-01-01 |
| * | 2014-01-03 |
|---+------------|
| _ |        Cnt |
| * |          1 |
#+TBLFM: $Cnt=vcount(@address@hidden)
#+END_SRC

After evaluation of the formula of $Cnt, the value is 1, not 2.

I found line 2715 of file org-table.el:

#+BEGIN_SRC
(setq form (replace-regexp-in-string org-ts-regexp3 "<\\1>" form))
#+END_SRC

change the value of `form' from `vcount([2014-01-01,2014-01-03]' to
`vcount(<2014-01-01,>)'. Is this the expected behavior?

Thank you very much in advance!
