unwrapping does not work correctly with latest org mode release

[ouboub]

Hi

given

| usando calculo     |
| simbólico          |
| pintar regiones de |
| estabilidad        |

the org-table-unwrap-cell-region

leads to

|   |
|   |
|   |
|   |
usando calculo simbólico pintar regiones de estabilidad

which is wrong

Ok
the following works (the docstring could explain this)

|-----------------------------------|
| usando RK implementar el disparo  |
| lineal para                       |
| condiciones de Dirichlet y Neuman |
|-----------------------------------|

gives

|--------------------------------------------------------------------------------|
| usando RK implementar el disparo lineal para condiciones de Dirichlet y Neuman |
|                                                                                |
|                                                                                |

so the hlines are needed. Moreover, if I have a table with various columns, I need to move the column with the
cells I want to unwrap to the left border of the buffer
