[PATCH 0/7] teach branch-specific options for format-patch

Currently, format-patch only accepts branch.<name>.description as a branch-specific configuration variable. However, there are many other options which would be useful to have on a branch-by-branch basis, namely cover letter subject and To: and Cc: headers.

Teach format-patch to recognise these branch-specific configuration options.

Note that this patchset[1] was created using these new configuration options:

	[branch "submitted/fix-revisions-txt"]
		coverSubject = "cleanup revisions.txt"
		cc = "Andreas Heiduk <asheiduk@gmail.com>"
		cc = "Duy Nguyen <pclouds@gmail.com>"
		cc = "Junio C Hamano <gitster@pobox.com>"

So this is a live example of this patchset working in practice.
