[PATCH] Ensure list insertion method does not depend on position of --merge-order argument

[Jon Seymour <jon.seymour@gmail.com>]

This change ensures that git-rev-list --merge-order produces the same result
irrespective of what position the --merge-order argument appears in the argument
list.

Linus: if you'd prefer to fix this a different way, that's fine by me!
