[PATCH 1/5] rebase -r: demonstrate bug with conflicting merges

flat view

From: Johannes Schindelin <redacted>

When calling `merge` on a branch that has already been merged, that
`merge` is skipped quietly, but currently a MERGE_HEAD file is being
left behind and will then be grabbed by the next `pick` (that did
not want to create a *merge* commit).

Demonstrate this.
