    # Quickly create and switch to a branch that follows your naming
    # convention:    <user>_<MM_DD>_<slug>
    #
    #   * <user>  : your git user.name with spaces replaced by underscores
    #   * <MM_DD> : current month & day (e.g., 05_26)
    #   * <slug>  : whatever you pass to `git new`, automatically lower‑cased
    #               and spaces changed to dashes.
    #
    # Example:
    #   $ git new "analytics endpoint"
    #   # on May 26 the branch becomes:
    #   #   nsheils_05_26_analytics-endpoint
    #
    # First push will create the upstream automatically because we set
    #   push.autoSetupRemote=true        (see above)
