wl-summary-resend-use-cache

[David Abrahams <dave@boostpro.com>]

The title variable is not clearly documented.

info wanderlust sez:

  `wl-summary-resend-use-cache'
       The initial setting is `nil'¡£If non-nil, messages are resend using
       cache even in the offline status. Note that if you use cache, the
       message identity is not guaranteed.

while `M-x describe-variable <RET> wl-summary-resend-use-cache' sez:

  *Non-nil to enable offline resending by using file cache.
  Note that strict message identity is not guaranteed when cache is used.

The former makes it sound as though, if wl-summary-resend-use-cache is
nil, you can resend when offline, but it won't "use the cache," whatever
that means.  The latter makes it sound like you can't resend when
offline if wl-summary-resend-use-cache is nil.

Neither description explains why the cache is relevant to resending when
offline, and neither explains what it means for message identity to be
guaranteed.  Could someone clarify these points (on the list and in the
docs)?

Thanks,
