[mew-int 00651] threading behaviour

[R.P. Aditya]

One of the nice (or broken depending on your point of view) features
that mutt has and I miss in mew is threads built not just based on
In-Reply-to/References headers but also on the Subject header (mutt
marks the message as a "possible" member of the thread); it would be
nice to have a mew variable to turn something like this on.

While we're on the subject of threads, is there any way to "x"ecute
deletes while remaining in thread mode?

Thanks,
Adi
