The header removal code looked for the colon for key-value at the wrong place, so it would overzealously remove headers. Tweak that condition, and make the alternative condition only active if it's set (with the remove prefix op case). Fixes phpGH-21018.

Looks correct to me otherwise, as a person who doesn't know this code well.

I find the name header_len very confusing. Maybe rename to prefix_len? It doesn't just include the header name fwiu.

Good point, this is pretty confusing. Not sure what I was thinking then...
