peek(n): If n is less than 0, None, or not set; return buffer contents with out advancing stream position. If the buffer is empty read a full chunk and return the buffer. Otherwise return exactly n bytes up to chunk size(not contents) with out advancing the stream position. If the buffer contents is less than n, buffer an additional chunk from the "raw" stream before hand. If EOF is encountered during any raw read then return as much as we can up to n. (maybe I should write that in code form??)

This proposal looks reasonable to me. Please note that it's too late for 3.1 anyway - we're in release candidate phase. Once you have a patch, you can post it on the bug tracker.

Regards

Antoine.
