As Ralph pointed out, bash simply does not have anything to do with
truncating the output ... if it's a Unix pipe it's not even involved
(after the file descriptors are established).

Now, there is a wrinkle here.  _IF_ you're using scan(1), by default it
will truncate output at the terminal width.  See the -width option to
scan(1) to change that.  Buuutttt .... IF you're doing whom(1) on the
draft, then a) every email address ends up on it's own line, and b) whom(1)
(really, post(8)) does NOT truncate the output at the terminal width.
I looked at the code AND I just double-checked that to make sure.  So
it sure would be interesting to understand exactly what is happening.
