I have noticed that some commits are extremely large, all of the file changed. In the mailinglist for commits, it shows the whole file. The web interface for the cvs repository only shows a few lines changed in such file though.
I suspect that the difference is different styles of newlines. Is there a policy for what sorts of newlines that should exist in the WordPress source? It would atleast make it alot less spammy in the mailinglist and easier to find the relevant changes.
