[O] Bug in org-table-convert-region?

[Thorsten Jolitz]

Hi List,

using 'M-: (org-table-convert-region beg end 2) on this output (with
beg/end being the points before and after the tabular data)

,-------------------------------------------------------------------
| === Error on training data ===

| Correctly Classified Instances         147               98      %
| Incorrectly Classified Instances         3                2      %

| Root relative squared error             22.9089 %

`-------------------------------------------------------------------

I get what I want:

| Correctly Classified Instances   |       144 | 96 | % |
| Incorrectly Classified Instances |         6 |  4 | % |
| Kappa statistic                  |      0.94 |    |   |
| Mean absolute error              |     0.035 |    |   |
| Root mean squared error          |    0.1586 |    |   |
| Relative absolute error          |  7.8705 % |    |   |
| Root relative squared error      | 33.6353 % |    |   |
| Total Number of Instances        |       150 |    |   |


However, using 'C-u 2 M-x org-table-convert-region' on the marked region
yields this:

| Correctly   | Classified | Instances |       144 |      96 | % |
| Incorrectly | Classified | Instances |         6 |       4 | % |
| Kappa       | statistic  | 0.94      |           |         |   |
| Mean        | absolute   | error     |     0.035 |         |   |
| Root        | mean       | squared   |     error |  0.1586 |   |
| Relative    | absolute   | error     |    7.8705 |       % |   |
| Root        | relative   | squared   |     error | 33.6353 | % |
| Total       | Number     | of        | Instances |     150 |   |

>From the comment-string:

,-----------------------------------------------------------------------
| (org-table-convert-region BEG0 END0 &optional SEPARATOR)
|
| Convert region to a table.[...]
| SEPARATOR specifies the field separator in the lines.  It can have the
| following values:
|
| '(4)     Use the comma as a field separator
| '(16)    Use a TAB as field separator
| integer  When a number, use that many spaces as field separator
| nil      When nil, the command tries to be smart and figure out the
`-----------------------------------------------------------------------

and from the elisp manual:

,-----------------------------------------------------------------------
| Here are the results of calling display-prefix with various raw prefix
| arguments:
|
|      C-u     M-x display-prefix  -| (4)
|
|      C-u C-u M-x display-prefix  -| (16)
|
|      C-u 3   M-x display-prefix  -| 3
`-----------------------------------------------------------------------

Looks like a bug in the argument handling?
