that should be help config.ui.allowemptycommit as in:

$ hg help config.ui.askusername
    "askusername"
        Whether to prompt for a username when committing. If True, and neither
        "$HGUSER" nor "$EMAIL" has been specified, then the user will be
        prompted to enter a username. If no username is entered, the default
        "USER at HOST" is used instead. (default: False)
