patch to prevent radixRegex catching empty strings
This was included in a previous patch but overlooked in the merging.
radixRegex in AbuseFilterParser::nextToken currently throws empty string
matches against non-numeric data. Those matches are later discarded by another
part of the code, but because it is overmatching the number finding code
profiles as the 2nd or 3rd most expensive block in nextToken even though
numbers are relatively rare.
The attached patch prevents empty string matches.
