[PATCH 0/2] format-patch --cover-letter improvements

This patch pair brings two improvements to the cover letter:

	- when calling format-patch with a diff option, this options
	  will be heeded by the cover-letter's diffstat, and

	- the onelines in the shortlog are wrapped around, just like
	  in Junio's "What's in ..." messages.

Johannes Schindelin (2):
  format-patch: use the diff options for the cover letter, too
  format-patch: wrap cover-letter's shortlog sensibly
