When a user visits https://en.wikipedia.org/wiki/Special:NewPages, the pagination links (e.g., "older 50") are currently broken. The HTML source looks like this:
<a href="/w/index.php?title=Special:NewPages&offset=20120827231315&limit" title="Special:NewPages" rel="next" class="mw-nextlink">older 50</a>
So when the user clicks the "older 50" link, he or she is taken to https://en.wikipedia.org/w/index.php?title=Special:NewPages&offset=20120827231315&limit.
The &limit is implicitly &limit=0, so no results are shown. This is broken behavior. &limit should not be in the URL at all when the user clicks "older 50" from Special:NewPages.
