rebase -i: demonstrate bugs with fixup!/squash! commit messages

When multiple fixup/squash commands are processed and the last one causes merge conflicts and is skipped, we leave the "This is a combination of ..." comments in the commit message. Noticed by Eric Sunshine. This regression test also demonstrates that we rely on the localized version of # This is a combination of <number> commits to contain the <number> in ASCII, which breaks under GETTEXT_POISON.
