patch, 2 partsAdd "-m" and "-F" options to "git notes edit"

Hi,

(This is a resend of an earlier series which got positive feedback from Dscho, but which has yet to show up in 'pu'.)

The following 2-patch series teaches "git notes edit" to support the "-m <msg>" and "-F <file>" options (inspired by git-tag and git-commit).

The first patch does some minor bugfixes and cleanups in preparation for the second patch, which adds the options with associated documentation and selftests.

This series is based on top of the "js/notes" topic in a recent "pu".
