# Issue

Remove lines other than commit title from syncing

# Description

SERVER-90928 Remove lines other than commit title from syncing to the
public repo

# Testing

This was tested locally. I tested on the commits in this PR and it seems
to be synced correctly. The staging file I used was
```
# This configuration is for migrating code from one Git repository to another using Copybara.
# It selectively copies content, excluding specific paths and preserving authorship.

# To test locally
sourceUrl = "/Users/alexander.neben/workspace/mongo2"
destinationUrl = "/Users/alexander.neben/workspace/mongodb-mongo"

# sourceUrl = "git@github.com:10gen/mongo.git"
# destinationUrl = "git@github.com:10gen/mongo-copybara.git"

core.workflow(
    name = "default",
    origin = git.origin(
        url = sourceUrl,
        ref = "IamXander/prune_commit",
    ),
    destination = git.destination(
        url = destinationUrl,
        fetch = "IamXander/prune_commit",
        push = "IamXander/prune_commit",
    ),
    # Change path to the folder you want to publish publicly
    origin_files = glob(["**"], exclude = ["src/mongo/db/modules/**"]),
    authoring = authoring.pass_thru("MongoDB <mongodb@mongodb.com>"),
    mode = "ITERATIVE",
    # Change the path here to the folder you want to publish publicly
    transformations = [
        metadata.scrubber("(^.*?)\n((\n|.)*)", replacement = "$1"),
    ],
)
```

Running git log on `/Users/alexander.neben/workspace/mongodb-mongo`
returns the following
