git-apply --reject
With the new flag "--reject", hunks that do not apply are sent to the standard output, and the usable hunks are applied. The command itself exits with non-zero status when this happens, so that the user or wrapper can take notice and sort the remaining mess out. Signed-off-by: Junio C Hamano <junkio@cox.net>
