Fix corner case bug with strip_quote().

strip_quote(), which is called by pattern_compare() did not properly
handle empty query string case. In the worst case it could wipe out
memory after a pointer returned from malloc(), which could cause a
segmentation fault in free() called in pattern_compare().

Per bug 458.
