Indeed,

I was confused because I found some 
HEAD=`$FORMAIL -X "" |sed -e 's/</\&lt;/g'`
type recipes in best-of-procmail.....
Does such formart also occasionally work?

I am not much sure about :0 things yet.
How often do I need it?
Do I need to :0 each time I formail as follows?
Or is there better way?

:0h
   RSUBJECT=|$FORMAIL -rtxSubject:
:0b
   RBODY=|$FORMAIL -I "" | sed 's/^/>/'
:0h
   HEAD=|$FORMAIL -X "" |sed -e 's/</\&lt;/g'
:0b   
   BODY=|$FORMAIL -I "" |sed -e 's/</\&lt;/g'
