wptexturize screwing some urls

[MattRead]

wptexturize screwing some urls, the line in wptexturize is:

$curl = preg_replace('/(\d+)x(\d+)/', "$1×$2", $curl);

for some urls like ​http://4x4blah.com/ etc., it replaces the 'x' with ×, which obviously screws up some links. So urls should not be filtered through that func or remove that line...

Specifically the bloginfo filter passes all bloginfo calls through wptexturize ...
