Subject: [BUGFIX] Shortcut redirect ignores linkVars syntax
X-Git-Tag: TYPO3_4-7-0beta1~86

[BUGFIX] Shortcut redirect ignores linkVars syntax

Currently the code that creates the redirect url for a shortcut
page only respects the linkVars option as list of parameters without
additional validation informations like it's documented in the
TSRef. Unfortunatly such paramaters are completely dropped and
this leads to major problems on multilanguage sites with the new
shortcut redirect feature.
