I'm trying to upload from a named pipe using the curl command-line tool.
I know the size of the content coming through the pipe, and want to
provide it in the Content-Length field. However, even if I provide my
own value for Content-Length, curl insists on providing its own (0-byte)
value in addition:

$ curl -vv "URL_REDACTED" \
          -X PUT \
        -T <(bfr -b 20 --speedcap 10 --minimum=10 "${FILE}") \
        -H "Content-Length: $(stat -c '%s' "${FILE}")"
* About to connect() to localhost port 2080 (#0)
* Trying 127.0.1.1... connected
* Connected to localhost (127.0.1.1) port 2080 (#0)
* Server auth using Basic with user 'USER_REDACTED'

OpenSSL/0.9.8g zlib/1.2.3.3 libidn/1.1
> Host: localhost:2080

> Content-Length: 7515
> Content-Length: 0
> Expect: 100-continue

The second "Content-Length: 0" header overrides the "Content-Length:
7515" on my server. How should I avoid this?
