In my single pass read through, I was able to understand everything. I
haven't sat down for a full analysis to make sure you covered all edge
cases.

Also, I don't think this is all correct reST syntax (:SHA1:, for
example). reST doesn't care, but it also doesn't do anything with it.

...

I'm not sure about having a transmission level hash check (:DELTASHA1:)
versus having full-text checks. Transmission level checks only let you
know that your TCP connection works (which has its own CRC +
retransmission checking), so it doesn't seem to gain much, versus
knowing that after applying all patches, your text is correct.

Overall, I think it is well written, and certainly worthy of becoming a
core developer doc.
