Revision b60df87a6b39b3e9fc2fe81585a8bc55a502dcd3 authored by Stephen Boyd on 22 March 2009, 04:32:43 UTC, committed by Junio C Hamano on 22 March 2009, 05:45:28 UTC
For example: git format-patch --numbered-files --stdout --attach HEAD~~ will create two messages with files 1 and 2 attached respectively. Without --attach/--inline but with --stdout, --numbered-files option can be simply ignored, because we are not creating any file ourselves.
