A new page has a diff link on Special:Contributions. I think it is better to unlink and show only the text, in the same way to Special:Watchlist.
Shouldn't be hard to do in theory; we're currently marking new pages in contribs with an 'N' so we should be able to drop the diff link. This check is based on checking getParentId() (rev_parent_id) for === 0; so that should be reliable for newer edits. Very old edits predating the use of this field will have null and just not be able to indicate whether they were first-edits or not.
Fixed in r57727.
