Calling `opkg update` several times will download package lists each time.
When there is a need to check for updates continuously it could lead to download big amount of redundant data.
It would be great if `opkg update` could check if package list had been changed on the server by downloading only HTTP HEAD before actual downloading.

This would definitely be beneficial, it's less important than fixing some of the current bugs though.

The implementation of this enhancement should include a way for a system admin to disable the optimization (force re-downloading the index). This could maybe be a per-source tag?
