[PATCH v4] format-patch --signature-file <file>

[Jeremiah Mahler <jmmahler@gmail.com>]

v4 of patch to add format-patch --signature-file <file> option.

This revision includes more suggestions from Jeff King:

  - Added a format.signaturefile config option.

  - Fixed error messages, --signature and format.signature

  - Fixed error checking, dies if strbuf_read_file fails.

  - style: "cat > expect << EOF" to "cat >expect <<-\EOF"

  - Eliminated use of fgrep, which is not used anywhere else
	in the project.  Possibility of portability problems.
    Replaced with sed which is commonly used.

  - Eliminated use of diff in favor of test_cmp.

  - Removed redundant test, "--foo=bar" and "--foo bar"

  - Changed to use test_must_fail instead of "!"
