\_ learn how to trim your replies please

This was funny.  I run into this a lot as a parent, mostly from the
other side.... "do as I say, ...."

Scoreboard:
sigs:     5
headers:  4
bodies:   8
plug-footers: 8

list-maintainers: is there something we can do to auto strip reply'd
footers?  (but still keep the "new" footer)
