Proposed Accept-Encoding header filter change.

[whenever]

1. Empty Accept-Encoding is permitted. See http://tools.ietf.org/html/rfc2616#section-14.3

2. The filter changes

Code:

Accept-Encoding: pack200-gzip, compress

to

Code:

Accept-Encoding: gzip

Which I think is not expected.

3. Why not remove x-gzip?

Besides the issue that Graycode has pointed out, x-gzip seems to be outdated. See http://en.wikipedia.org/wiki/HTTP_compression & http://tools.ietf.org/html/rfc2616#section-3.5
