Subject: git-remote-mediawiki: allow page names with a ':'
X-Git-Tag: v1.7.12-rc0~8^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=2272400c93332629e8c34dcf3b1207159352e539;p=git.git

git-remote-mediawiki: allow page names with a ':'

Traditionnally, pages named Foo:Bar are page 'Bar' in namespace 'Foo'.
However, it is also possible to call a page Foo:Bar if 'Foo' is not a
namespace. In this case, the actual name of the page is 'Foo:Bar', in the
main namespace. Since we can't tell with only the filename, query the
wiki for a namespace 'Foo' in these cases, but deal with the case where
no such namespace is found.
