Another thing I forgot to mention, even in the documentation. Currently all the diff-tree family says -M and -C imply -p which is by itself sensible, because rename-edit and copy-edit cannot be expressed with the diff-raw format (the format only takes one path).

On the other hand, pickaxe is really a diff filter, so it can work with both diff-raw and diff-patch format. Here is my favorite example, in git.pasky aka cogito archive:

    ./git-rev-list pasky |
    ./git-diff-tree --stdin -S'static const char *tag_cached = "";
    static const char *tag_unmerged = "";
    static const char *tag_removed = "";'
