Multi-line comments and comment-region

[Thorsten Jolitz]

Hi List, 

when I uncomment this in a C buffer

,----------------------------------------------------------------------
| /* Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Donec
| hendrerit tempor tellus. Donec pretium posuere tellus. Proin quam
| nisl, tincidunt et, mattis eget, convallis nec, purus. Cum sociis
| natoque penatibus et magnis dis parturient montes, nascetur ridiculus
| mus. Nulla posuere. Donec vitae dolor. Nullam tristique diam non
| turpis. Cras placerat accumsan nulla. Nullam rutrum. Nam vestibulum
| accumsan nisl. */
`----------------------------------------------------------------------

and then call comment-region on it again, I get:

,-----------------------------------------------------------------------------
| /* Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Donec */
| /* hendrerit tempor tellus. Donec pretium posuere tellus. Proin quam */
| /* nisl, tincidunt et, mattis eget, convallis nec, purus. Cum sociis */
| /* natoque penatibus et magnis dis parturient montes, nascetur ridiculus */
| /* mus. Nulla posuere. Donec vitae dolor. Nullam tristique diam non */
| /* turpis. Cras placerat accumsan nulla. Nullam rutrum. Nam vestibulum */
| /* accumsan nisl. */
`-----------------------------------------------------------------------------

Where/how is this behaviour controlled? Is that major-mode specific or
generic (for all modes with different comment-styles including
multi-line comments)?

Which style is the recommended one?
