format-patch: add --description-file option
This patch makes it possible to directly feed a branch description to
derive the cover letter from. The use case is formatting dynamically
created temporary commits which are not referenced anywhere.
The most obvious alternative would be creating a temporary branch and
setting a description on it, but that doesn't seem particularly elegant.
