This patch addresses an issue with the IPFire WebGUI adding a space
after every 80 characters in the display of long log entries on the
"Logs/System Logs" page.  (Bug 13735)

The patch removes the "very basic breaking of lines..." code and replaces it
with a direct copy of the log entry $data to the display output variable $d.

Removing these lines seems fine to me. The code looks to be adding a 
space instead of doing an actual line break. The text is also auto word 
wrapped in the text box in the browser anyway.

My only question is why you left all the removed lines in place as 
comments, rather than just removing them completely?
> +	my $d = $data; #don't break lines for display
I think you could also save a line by not having this line but changing 
the earlier line of
$data = $2.': '.$data;

to

my $d = $2.': '.$data;

Hi Adolf,

Thanks for your help on this.

I left the original code lines in place for context.  They're not really necessary.  If it's better, I can remove them and resubmit the patch.

For the 

my $d = $2.': '.$data;

suggestion, there is some special processing for the display for the RED section logs.

        # correct the cut position, just when section=RED
        if (($cgiparams{'SECTION'} eq 'red' ) && ($sec =~ /(kernel:)(.*)/)) {
            $sec = 'kernel';
            $data = $2.': '.$data;
        }

Using 'my $d = $2. ': ' .$data;' for everything would add the timestamp to the front of the log text displayed for all sections.

I'm not sure if the special processing for $data for RED is necessary.  I think that the point of the 'if' statement is to clean up the Section display for entries from 'kernel: ippp\d' and 'kernel: isdn.*' matches for RED, but I don't know why adding the timestamp to the front of data would be desirable in that specific case.  I don't have any log entries to reference for that though.

Thanks,
Stephen

I think it would make more sense to remove them.

You will need to make it a v2 patch so it supersedes this one automatically in patchwork.

I hadn't seen the special processing for the RED section logs.

I would leave it as you have done it then unless Michael or Arne or Peter come back further on  this.

Let's keep it simple for now.

I think we can safely drop this as we no longer support ISDN.
