49 it will be killed sometime later."
54 "*Non-nil means that Gnus will try to build threads by grabbing old headers.
55 If an unread article in the group refers to an older, already read (or
56 just marked as read) article, the old article will not normally be
57 displayed in the Summary buffer. If this variable is non-nil, Gnus
58 will attempt to grab the headers to the old articles, and thereby
59 build complete threads. If it has the value `some', only enough
60 headers to connect otherwise loose threads will be displayed. This
61 variable can also be a number. In that case, no more than that number
62 of old headers will be fetched. If it has the value `invisible', all
63 old headers will be fetched, but none will be displayed.
65 The server has to support NOV for any of this to work."

80 "*nil means that Gnus won't gather loose threads.
81 If the root of a thread has expired or been read in a previous
82 session, the information necessary to build a complete thread has been
83 lost. Instead of having many small sub-threads from this original thread
84 scattered all over the summary buffer, Gnus can gather them.
86 If non-nil, Gnus will try to gather all loose sub-threads from an
87 original thread into one large thread.
89 If this variable is non-nil, it should be one of `none', `adopt',
90 `dummy' or `empty'.
92 If this variable is `none', Gnus will not make a false root, but just
93 present the sub-threads after another.
94 If this variable is `dummy', Gnus will create a dummy root that will
95 have all the sub-threads as children.

109 "*A regexp to match subjects to be excluded from loose thread gathering.
110 As loose thread gathering is done on subjects only, that means that
111 there can be many false gatherings performed. By rooting out certain
112 common subjects, gathering might become saner."
117 "*Maximum length of subject comparisons when gathering loose threads.
118 Use nil to compare full subjects. Setting this variable to a low
119 number will help gather threads that have been corrupted by
120 newsreaders chopping off subject lines, but it might also mean that
121 unrelated articles that have subject that happen to begin with the
122 same few characters will be incorrectly gathered.

125 comparing subjects."

291 newsgroup will be selected without any confirmation, and if it is
292 `almost-quietly', the next group will be selected without any
