Bug: web review diff not aware of hg rename

[Weijun Wang]

Hi All

I 'hg rename' a file in my repo and then edit it. After the new commit,
'hg tip -p' very nicely shows:

diff --git a/targ b/resp
rename from targ
rename to resp
--- a/resp
+++ b/resp
@@ -1,7 +1,7 @@ 1

However, the 'hg serve' web version shows:

--- /dev/null

which seems unaware of the rename action.

Thanks
