git-diff doesn't understand :<stage>:<filename> and :<filename> for
accessing index version of blob (git-cat-file for example understands
it).

You probably got this impression from a botched experiment or
something, but this statement is wrong as demonstrated above.

Right, sorry.

And you can write ./<filename> to distinguish it from revision name, so
proposed ::<filename> extension is not needed.
