The custom user-agent option is ignored after the initial connection when using HTTP Live Streaming (HLS)

The "-user-agent" option is ignored after the initial connection to an HLS server.

When running this command line:
ffmpeg -user-agent myuseragent http://someserver/playlist.m3u8 -c copy -

I get this network dump for the initial connection to someserver:

GET /playlist.m3u8 HTTP/1.1.
User-Agent: myuseragent

But in the (automated) consecutive connections (after the initial .ts segments are consumed) I see this:

GET /playlist.m3u8 HTTP/1.1.
User-Agent: Lavf54.3.100.

Which means that the custom user-agent option is somehow ignored after the initial connection to the server.

Version: ffmpeg version N-40092-g3bbf3f7

Replying to cehoyos:

Please add complete, uncut console output.

This snippet:

GET /playlist.m3u8 HTTP/1.1.
User-Agent: Lavf54.3.100.

is observed via the network diagnostics tool "tcpdump" and not the console.

The console does not output anything regarding the user-agent at all.
But here it is:

I passed user-agent "User-Agent: My MX Player/1.0" within other custom headers (cookie) with url "":

The first request was sent as expected:

GET / HTTP/1.1
Accept: */*
Connection: close
User-Agent: My MX Player/1.0
Cookie: mobileuser=blapp

But the subsequence requests ignored the custom headers:

GET / HTTP/1.1
User-Agent: Lavf54.63.102
Accept: */*
Connection: close
