Strange line-wrapping

Strange line-wrapping

[Fredrik]

Using NTemacs 21.2.1 I have the following problem:

I like to have my code wrapped automatically so I've set c-ignore-auto-
fill to nil which works pretty well. However, there is some strange 
behaviour. This works fine:

int Method(int parameter1, int  <---- automatic wrap
           parameter2, int parameter3)
{
}


But if ther is a comment before the line to wrap, I get the following 
result:

//----------
//Comment
//----------
int Method(int parameter1, int  <---- automatic wrap
//parameter2, int parameter3)   <---- now this is a comment!
{
}


ie the comment-signs (//) is added to the new line. 

Can someone explain this? And how do I solve it?

Regards
//Fredrik

Explanation is easy: Emacs takes the fill prefix (the "//" is a fill
prefix) from the second line of each paragraph.  That way, you can do
stuff like the following

        Look, this is a paragraph where the first line is indented
    eight spaces and all subsequent lines are indented four spaces.
    I can just keep on typing and the indentation will be correct.
    The four spaces that get inserted automatically in front of each
    line are the fill prefix.

Tell Emacs that each non-comment line is the start of a new
paragraph: see variable paragraph-start, and also paragraph-separate,
perhaps.

Looking up the variables tells me their values are

"[ 	]*\\(//+\\|\\**\\)[ 	]*$\\|^\f"

and

"[ 	\f]*$"

As my emacs-knowledge is rather limited, I have no idea on how to 
interpretate this information. Can anybody help me?

BTW Kai, emacswiki (http://www.emacswiki.org/cgi-bin/wiki.pl?
IndentationTutorial) tells me you have an indentation-tutorial at 

http://ls6-www.cs.uni-dortmund.de/~grossjoh/emacs/tutorials.html

When trying to view that page, the server tells me I don't have 
permission to access it. Is this correct, i.e. I should not have access 
to it, or is there an error?

I apologize.  I've recently changed jobs and getting my web page back
up has had a too low priority to get done already.

First, I was lacking a chair and a desk.  Then I was lacking a
pencil.  Now I'm still lacking an eraser and a trash can...  :-)
