Subject: LoginSignupSpecialPage: Load return and returnto params as early as possible
X-Git-Tag: 1.31.0-rc.0~6775^2
X-Git-Url: http://git.cyclocoop.org/%7B%24admin_url%7Dcompta/comptes/journal.php?a=commitdiff_plain;h=3d1e04e976ccb27e22e71ee0cd8ba53ee2d90780;p=lhc%2Fweb%2Fwiklou.git

LoginSignupSpecialPage: Load return and returnto params as early as possible

They're are needed for a redirect to the target page after
a successful login, which is made before the SpecialPage::execute()
function is called. Loading basic request varaibles in the execute()
function is therefore too late to take effect for the redirect after
a successul authentication with a primary provider, which needs to
redirect the user to another site.
