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. Multiple "-m" and/or "-F" options are concatenated as separate paragraphs. The patch also updates the "git notes" documentation and adds selftests for the new functionality. Unfortunately, the added selftests include a couple of lines with trailing whitespace (without these the test will fail). This may cause git to warn about "whitespace errors". This patch has been improved by the following contributions: - Thomas Rast: fix trailing whitespace in t3301 Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
