 'git-update-cache' and 'git-read-tree' first - I wish I had!

-     <old|new>-mode are the octal representation of the file modes.

-   The file parameters can point at the user's working file (e.g. new-file
-   in git-diff-files), /dev/null (e.g. old-file when a new file is added),
-   or a temporary file (e.g. old-file in the cache).  GIT_EXTERNAL_DIFF
-   should not worry about unlinking the temporary file --- it is removed
-   when GIT_EXTERNAL_DIFF exits.
-
-   For a path that is unmerged, GIT_EXTERNAL_DIFF is called with
