[tex-live] texlive 2009 xindy make-rules compile problem

[Karl Berry]

    The only problem with "Reply to all" is that List-Id filters do not
    work with these e-mails.

This is all totally off-topic, but for those using procmail, you can
eliminate duplicates via Message-Id.

# One often receives duplicate messages for cross-postings to mailing
# lists, or explicit replies to a post from you in addition to the
# mailing list message.
# 
# The following recipe eliminates all duplicate messages.  It tells
# formail(1) to keep a cache file of the Message-IDs of the most recent
# messages you've received.  Since Message-IDs are guaranteed unique for
# distinct messages, they are ideally suited to weed out duplicates.
# 
# all recipes start with `:0'.
# h - send headers only to the subprogram.
# W - wait for completion, suppressing `program failure' message.
# : - do locking.
