Subject: Test that stg coalesce handles head != top gracefully
X-Git-Tag: v0.15-rc1~138

Test that stg coalesce handles head != top gracefully

It currently doesn't quite: it will roll back the transaction just
fine, but not before asking the user for a commit message which is
lost in the rollback.
