Thanks for the answers
It's not so easy to add the hook, I'm not the admin of the repository, so I won't be able to add the hook, or change SVN to other SCM (in fact we use SVN and Mercurial)
Also I'm not in charge of the team, so I won't be able to convince the developers to use all the same line endings. I totally agree we should have standards, but it is not always so easy when there are lots of developers from different companies, and there is no unique team
So what I need is when I do a modification in a line, just modify that line, and leave the line endings as they are.
I think normalization of line endings is a great feature but I don't really need it, and I don't want it, so if there is no easy way to disable this feature I will look a little more if it is possible to do it through a plugin, but I don't have too much experience on plugins
Any idea on how to avoid the normalization through a plugin?
