Small clean up

Since I was messing around with Global Redirect already, I thought I'd clean it up a wee bit. So here is the result.

I felt like changing stuff such as if (variable_get('site_offline', 0) == 1) return FALSE; into

if (variable_get('site_offline', 0) == 1) {
  return FALSE;
}

as well, but realised I didn't know whether these one liners were preserved for keeping the processing time at a minimum, or... ? (If so, there's a place where a "multi-liner" could be changed into a "one-liner" - consistency please!) Pray let me know so I can alter the patch accordingly. Thank you. :)
