Re: 'Deepen' after "git clone --depth=1"?

Suppose I want to make a shallow clone of a repository for some
size-sensitive application. I may later want to fill out the complete
history of that repository, so that I can work with it as if I had
done a full-depth clone to begin with. Is there an existing porcelain
command/option to produce that effect? If not, is there a fundamental
reason why this couldn't be implemented? It looks like this is
something fetch-pack should be able to do, but its documentation
doesn't seem to describe how. Also, the man page for fetch appears to
lie, in that --depth=n (where n is greater than the clone depth)
doesn't have any noticeable effect.

Last time I've tried (1.6.x),
   git fetch --depth=n
indeed, did nothing, but
   git fetch --depth=n origin master
worked (deepened history; but it seems it redownloaded (some) objects).

If the answer is simply "no one's written the code to do it yet", I'll
be happy to provide the necessary round tuits.
