[Orgmode] Small bug in table editing

[Christopher Witte]

Hi,

I've been using the table editing feature of org mode, I never
realised plain text tables could be such fun to work with, and I just
came across a small bug. I had entered a table:

| Heading 1 | Heading 2 |
|         1 |         2 |
|        11 |        22 |


and then decided I wanted to go back and put a horizontal line after
the heading.  So I want to the start of the line after the heading and
entered "|-"

| Heading 1 | Heading 2 |
|-|         1 |         2 |
|        11 |        22 |

when I then pressed enter (or tab), the first line of data got eaten
up and replaced with the horizontal line like this:

| Heading 1 | Heading 2 |
|-----------+-----------|
|        11 |        22 |

This wasn't the behaviour I was expecting :).  While it is pretty
obvious to see what was going on in this example, if you have a long
table it isn't as obvious and I didn't notice until much later (emacs
undo in region saved the day).

Cheers,
Chris.
