It would seem that the majority of folks on the Git list feel that way, myself among them. I don't know that we'd find it an insult to say Git fully supports renames but I do think we have had better results from *not* recording them and looking for them after the fact with smart tools. Junio's recent work with git-pickaxe (or whatever its name finally settles out to be) is a perfect example of this. Despite not having "recorded renames" git-pickaxe is able to fairly accurately detect blocks of code moving between files, of which renaming files is just a special case. This provides some fairly accurate blame reporting pointing to exactly which commit/author/datetime put a given line of code into the project. No additional metadata required. All existing repositories can immediately benefit from the new tool. Rather slick if you ask me. -- Shawn.
