|Subject:||diff a/ b/ links do not always work (if file removed)|
If the file has been removed then the when viewing the diff: diff --git a/... b/... The links do not work (as the file doesn't exist in the HEAD), so ideally they shouldn't be links Also, should these links actually go through to a <sha1> in which they are relevant (e.g. the 'a' sha1 and the 'b' sha1)? - then so in the above example a/... would be a link, but b/.. wouldn't be?
