From: Ondrej Mosnacek <omosnace@xxxxxxxxxx>
When generating the patches under $SINGLE_TARBALL == 0, cherry-pick each
commit on top of $MARKER before generating the patch from it. This
partly solves the problem of patches generated from old commits not
applying on the current tree any more.
To avoid polluting the current working copy, this is done in a temporary
worktree inside a temporary directory, which is automatically deleted
when the script exits.
