Shallow clones (git clone --depth) are broken?

From: Jim Ramsay <hidden>

I've been trying to experiment with shallow clones, however I can't
seem to actually create one.  Here's what I've tried, for example:

git clone --depth 1 git://git.fluxbox.org/fluxbox.git

However, this gets me everything, and takes quite a while.  After it
completes, running gitk shows me the entire history, and the size of
the .git directory is the same as a full clone I've done previously.

I've tried this with both 1.6.0.2 and 1.6.1.3, to the same effect.

Can anyone out there verify that this --depth option actually does
anything?  Or could it potentially be the version of git on the
server?

If it's not just something odd I'm doing, I can take the time to
try to figure out in which version this *does* work, and when it
stopped... Though others out there may be more equipped than I to chase
this down.

Sorry, I can't reproduce (using 1.6.0.2):

There is some server support required for shallow clone; I didn't check,
but I assume that the client would degrade gracefully to a full clone.
In which case, is it possible that fluxbox.org upgraded since you
tested? Can you try again?
