Hello,

This patch allows curl to be able to send the custom headers with empty
value.
I badly need this function, but now latest curl can not.

If you put a space character after a colon then you can send its header.

curl -v -k -X POST -H 'X-Custom: ' http://to/

If you set no-blank after a colon then curl does not send any headers.
This is current specification, you know?

curl -v -k -X POST -H 'X-Custom:' http://to/

Please marge this to trunk.
