Going from RecentChanges, when viewing the diffs of newly created pages (like http://tinyurl.com/35f5q3 for the Allow web edit form comment field to be mandatory page, then there should -- in my opinion -- the diff for the newly added page be shown.
I don't see any way to make gitweb do that. You can click on the filename after the "diff -cc" to see the whole file output, but gitweb won't show a diff for a newly added file. --Joey
happily this, too, is fixed by using the new style gitweb urls. done --Joey
