Setting $wgArticlePath to something like "wiki/$1" accidentally can cause a lot of hassle to people setting up short urls. There is absolutely no valid reason to set $wgArticlePath to a relative path. We should make Setup.php or some other part of MW bail out early with an informative error message if it is not absolute.
Change 135196 had a related patch set uploaded by devunt: Validates wgArticlePath does start with slash (/). https://gerrit.wikimedia.org/r/135196
