[PATCH v1 4/4] miscellaneous: avoid "too many arguments"

[Junio C Hamano <gitster@pobox.com>]

Imagine seeing your command failing with "too many arguments" when
you run "git cmd foo bar baz".  Can you tell it will work if you
said "git cmd foo bar"?  Or is that trimming your command line too
much?  Too little?

Instead, if the command reports "unknown argument: 'bar'", you'd know
that "bar" and everything after it is unwanted.

Let's make it so for a few remaining commands.
