Weird behavior of git rev-parse

Hi,

instead of `git rev-list -2 HEAD` I've tried `git rev-parse -2 HEAD` just to see the effect of -N in rev-parse, but I've got this output:

    -2
    0294cdd1e2c5535f5b87eff4a1aff3390e03af39

Then I've tried

    $ git rev-parse -'hi, this is a test!'

the output is:

    -hi, this is a test!

Is this an expected behavior?

Another questions is, usage is printed if you omit the commit id in git rev-list (E.g. `git rev-list -2`). Is there a reason why HEAD is not taken as the default?
