I did this

I want to disable an automatically generated header (e.g. "Host") and send an empty header instead:
/curl -v -H 'Host;' 'http://www.example.com'

I expected the following

I expected that curl sends a "Host" header with an empty value. Instead, it sends two "Host" headers, the default one ("Host: www.example.com") and the custom one ("Host:").

As a workaround, it's possible to send just the custom one with this command:
curl -v -H 'Host:' -H 'Host;' 'http://www.example.com'

curl/libcurl version

curl 7.59.0-DEV

Good find! This is clearly a mistake and we should fix it and add a test case or two for it...
