speed up hg log --patch
Changing dodiff to read the manifest/changelog for node1 before calling
repo.update allows us to take advantage of the revlog revision cache.
Before this patch and my previous "speed up hg log --debug" patch, when
using hg log -p to display three revisions (A, B and C), dodiff and
repo.changes would end up reading the manifests in this order:
B A B A C B C B
With both patches, this order becomes:
A A B B B B C C
(This considers only dodiff and repo.changes. I'm not sure how other
parts of hg log enter the picture.)
The speed up will depend on the revisions being displayed. (All
"before" times already have my previous "speed up hg log --debug" patch
applied.)

c84c2069592f was the tip of a 10 day old kernel repo that I had lying
around and was where I first tested this patch. For some weird
coincidence it's also a place where the patch makes a huge difference.
