I'm not familiar with formail.  I assume that this usage of it removes
all of the headers, in which case, the remainder would start with an
empty line.  I assume you mean "BODYSUB begins with a <LF>...".

Why not just delete the empty line by using:

     BODYSUB=`formail -I "" | tail -n +2`

Of course, this turns the first line of the body into the subject line.
There will also be trouble if the body contains more than one line.

It would be easier to help you if you explained exactly the
transformation you want to accomplish, and also gave an example.
