gnus-fetch-old-headers
nil
, Gnus will attempt to build old threads by fetching
more old headers--headers to articles marked as read. If you
would like to display as few summary lines as possible, but still
connect as many loose threads as possible, you should set this variable
to some
or a number. If you set it to a number, no more than
that number of extra old headers will be fetched. In either case,
fetching old headers only works if the back end you are using carries
overview files--this would normally be nntp
, nnspool
,
nnml
, and nnmaildir
. Also remember that if the root of
the thread has been expired by the server, there's not much Gnus can do
about that.
This variable can also be set to invisible
. This won't have any
visible effects, but is useful if you use the A T command a lot
(see section 3.22 Finding the Parent).
gnus-fetch-old-ephemeral-headers
gnus-fetch-old-headers
, but only used for ephemeral
newsgroups.
gnus-build-sparse-threads
some
. Gnus will then look at
the complete References
headers of all articles and try to string
together articles that belong in the same thread. This will leave
gaps in the threading display where Gnus guesses that an article
is missing from the thread. (These gaps appear like normal summary
lines. If you select a gap, Gnus will try to fetch the article in
question.) If this variable is t
, Gnus will display all these
"gaps" without regard for whether they are useful for completing the
thread or not. Finally, if this variable is more
, Gnus won't cut
off sparse leaf nodes that don't lead anywhere. This variable is
nil
by default.
gnus-read-all-available-headers
nnultimate
groups.
If you don't use those, then it's safe to leave this as the default
nil
. If you want to use this variable, it should be a regexp
that matches the group name, or t
for all groups.
