[PATCH 2/2] Teach "-m <msg>" and "-F <file>" to "git notes edit"

From

In-Reply-To
<200904210239.21974.johan@herland.net>

The "-m" and "-F" options are already the established method (in both git-commit and git-tag) to specify a commit/tag message without invoking the editor. This patch teaches "git notes edit" to respect the same options for specifying a notes message without invoking the editor.

The patch also updates the "git notes" documentation and adds a couple of selftests for the new functionality.
