Re: too many 'changed' entries

Hi All,

I finally found out the reason & solved my own problem.
Thank you very much, Mel, for turning me in the right direction!

It did, although not completely. Now I know that I caused the problem
by myself, by adding "-wrap=>'hard'" to the edit-fields. This was done
to preserve the format of an PR, esp. user-added line-breaks. Without
it I found no way to distinguish between user-added and gnatsweb-added
line-breaks. But it caused the following strange behaviour:
 - a soft linebreak was inserted as a single <CR><LF> sequence.
 - a hard (user-added) linebreak was inserted as <CR><LF><CR><LF><CR><LF>.

I found no way to avoid that. Finally I changed 'fix_multiline_val'
into the attached one. From then on, everything worked like I wanted:
 - Soft linebreaks do not make it into the PR
 - Hard linebreaks go into the PR as-is.

I send this to the list just in case someone else wants this behaviour
or stumbles over it. It's not a Gnatsweb bug but merely a perl-cgi bug.
But it seems the only way to get rid of it is a special version of
'fix_multiline_val'.

Have fun.
