Willy Tarreau 57c5ae10f6 SCRIPTS: mk-patch-list: produce a list of patches
There does not seem to be a convenient way to tell git-show-backports to
produce individual patches with numbers. That's what this script does by
calling git-format-patch for each specified commit ID, letting git do all
the painful work (formatting etc). This has been mostly used during
backport sessions but was apparently never committed!
