Problem: Imp actually tries to use Accept-Language and shows the value  
to users. Accept-Language does not really show what language the  
message is, but what language pack or locale sender uses.

Proposed solution: Ignore Accept-Language header and value it might  
have. Other mail clients do this already.

This bug is also present in development versions.

These mail clients just ignore the value in this header: Thunderbird,  
Outlook, Apple Mail App, Windows Phone 7 client, Symbian Mail Client.

Note that RFC 4021 recommends that Accept-Language might be useful in  
generating automatic replies:
Indicates a language that the message sender requests to be used for  
responses.  Accept-language was not designed for email but has been  
considered useful as input to the generation of automatic replies.

W3.org documentation does not recommend using Accept-Language alone to  
determine language:
