This is unrelated to git. The HTTP server's configuration is too
impatient.

It can't, because it doesn't know.

The error message doesn't really know whether it is going to overwrite
it (the CR comes from the server), though I suppose an extra LF wouldn't
hurt there.

You asked for the current state of the repository, and that's what its
giving you. The timeout has nothing to do with git, if you can't
convince the admins to increase it, you can try using another transport
which doesn't suffer from HTTP, as it's most likely an anti-DoS measure.

If you want to download it bit by bit, you can tell fetch to download
particular tags. Doing this automatically for this would be working
around a configuration issue for a particular server, which is generally
better fixed in other ways.
