The mailing list for listmasters using Sympa

[Russ Kepler <address@concealed>]

I think I pinned down the problem with the entire list receiving summaries, 
in List.pm in the procedure snd_msg_digest the line that sends the summary is 
thus:

    $self->send_file('summary', \@tabrcptsummary, $param);

With no condition and an empty list in @tabrcptsummary send_file must be 
blasting the message to the entire list.  I'm hoping that changing this to 
the following will remove the problem:

    $self->send_file('summary', \@tabrcptsummary, $param) if 
(!($#tabrcptsummary == -1));

(I found this while adding a 'digest-text' mode to the formats).
