Comment (by stevish):

 Here's one that will grab an empty variable at the beginning, end, or
 middle. I did a lot of testing, and couldn't fool it. Maybe someone else
 can see a problem with it?

 {{{'#(^|&)(p|page_id|cat|tag)=?$|(p|page_id|cat|tag)=&#'}}}

 Notice that when looking for an empty declaration in the beginning or
 middle (without requiring an "end of string"), it requires a '=&' at the
 end, without checking for one at the beginning. This will make sure we
 only remove one '&' per declaration, and conceivably, will never touch any
 set of letters directly following an '='.

 Any objections?
