Actually, AFAIK the normal "many functions" format looks like:

        * filename (functionname1, functionname2)
        (functionname3, functionname4)
        (functionname5, functionname6)
        (functionname7, functionname8): New functions.

we even tried to make the auto-fill code DTRT in the change-log-mode.
