Special:Whatlinkshere shows up to 500 direct links per page, with options for
"previous/next 500". For each incoming redirect, it additionally shows up to 500
links through that redirect. However, this second limit of 500 seems to be
unrelated to the first limit, and no "next 500" option is available. See
[[w:en:Liberal Democrats]], where there are under 500 direct links, but over
2000 through [[Liberal Democrats (UK)]], and there is no way of viewing all the
redirected links on [[Special:Whatlinkshere/Liberal Democrats]].
[[Special:Whatlinkshere/Liberal Democrats (UK)]] shows all the redirected links
