Hello,

I'm posting an empty content using chunked encoding:

$ ./curl-7.25.0/src/curl --trace - -d @empty.txt --header "Transfer-Encoding: chunked" http://172.16.19.0:8080

empty.txt is an empty file (created with "touch empty.txt").
The server is confused because curl sends 2 empty chunks instead of 1.

Is it the normal behavior or is it a bug ?

Thanks,
