It might not be completly clear, but I change the original code
"(\w[_-\w]*)" to "(\w[_\w-]*)". So I put the - at the end.

I understand, but I don't think it must be the first but can also be the
last, or be escaped by \ which will result in "(\w[_\-\w]*)".
At least the warning was gone when I changed the line.
Thank you for your information on this matter.
