If $wgArticlePath = "/w/$1"; then {{fullurl:Article|foo=bar}} should return http://www.mywiki.com/w/Article?foo=bar
and not http://www.mywiki.com/realInstallationPath/index.php?title=Article&foo=bar
just like [[Article]] links do.

I see no reason for different handling between fullurl and [[link]].

$wgActionPaths does not apply here since fullurl can take all kinds of parameters like foo=bar which can be used with urlget.
