I'll agree that being in interactive editor is a more conducive setting for this kind of message, but you can provide both a title and longer description via command line by specifying the -m option twice, e.g.

    git commit -m "fixed the widget factory" -m "It seems like we keep getting wooden shoes stuck in the machine, so I added a ShoeClearingDaemon process to check periodically and restart the machine if necessary."
