Please do not leave these four lines in your e-mail message, unless there is a good reason to do so (e.g. when you are forwarding a patch authored by somebody else, you may want a "From:" that names the real author at the beginning, but that does not apply in this case where you are sending your own). The first line is merely a marker to say the file is a format-patch output, and the header lines are there for those who use "git send-email" to mail the messages out, and/or for those who want to cut & paste some of them (not copy & paste) to their MUA header input widgets.
Instead of simply ignoring the value passed to --depth option when it is zero or negative, now it is caught and reported. This will let people know that they were using the option incorrectly (as depth<0 should be simply invalid, and under the hood depth==0 didn't have any effect). (The change in fetch.c is needed to avoid the tests failing because of this new restriction.)
Good, but it is not just tests but without that change real operations break. In other words, it is an integral part of the patch, not a workaround for a broken test. Thanks. Will queue with a bit of tweak.
