[PATCH 3/5] rebase -i: include MERGE_HEAD into files to clean up

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

Every once in a while, the interactive rebase makes sure that no stale
files are lying around. These days, we need to include MERGE_HEAD into
that set of files, as the `merge` command will generate them.
