line wrap in the index?

[Paul E Condon <pecondon@xxxxxxxxxxxxxxxx>]

I have several verbose correspondents who write little essays in the
Subject header.  If I could put Subject: field last, I could see
several fields, like From; that are more important. But these other
fields are variable lenth, and that messes up threading, which is
keyed to the start of the Subject: field in each line, I think.

But rather than line wrap in the index, is there a way to truncate the
print of the subject field?  I think I can tell whether I want to open
an email on the basis of the first twenty or thirty letters of the
subject.

Thanks,
