new_subject_breaks_threads
--------------------------

   Type: integer
   Default: 0

   In large threads, the tree built by looking at the ``References:'' can
   become quite complex and sometimes confusing. Thus, some people prefer
   to see a separate thread tree whenever the ``Subject:'' header line
   changes. Set this variable to 1 if you want this (more, but smaller
   trees).

   By default, slrn puts articles with identical subjects into the same
   thread, even if they are not linked by a ``References:'' header. If
   you want slrn to thread based on references only, set this variable to
   2 (also gives you more, but smaller trees). If you want to enable both
   of these features, use 3 as the value.

   Note: Before comparing subjects, a leading ``Re: '' and a trailing
   ``(was: ...)'' is cut off. However, the regular expressions in
   strip_re_regexp and strip_was_regexp are not used.
