I don't really like the "argv[0][0] == '-'" logic, but it doesn't seem
to have the flaw you pointed out:
$ ./git stash -this is a test-
error: unknown switch `t'
usage: git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet]
[...]
I'm not sure this is the best possible error message, but it's just as
useful as the message from the old version.

I think it's correct as is. One of the tests checks for this string to
be output, and if I move the line, the test fails.
I agreed with all the other points you raised, and they will be fixed
in my next revision.
