Added option that allows a signature file to be used with format-patch
so that signatures with newlines and other special characters can be
easily included.
$ git format-patch --signature-file ~/.signature -1
The config variable format.signaturefile is also provided so that it
can be added by default.
$ git config format.signaturefile ~/.signature
$ git format-patch -1
