thanks for the test. Yes, I forgot to mention that I used libcurl 7.18.0. I've just now compiled libcurl 7.18.2 and replayed your test. The second request looks then like:

GET / HTTP/1.1
Host: server
Accept: */*
Accept: moo

...still including two Accept headers. So with libcurl 7.18.2 I can still observe the unwanted behavior.
