Anybody want to fix ash's backspace line wrap?

They are.  Belt and suspenders.  I just got done putting in
BS-over-BOL and ^L repaint code in our product's shell (nothing
to do with Un*x shells), and I felt like I was transported back
25 years...  But as one of the few around here (not the BB list)
that did this crap the first time around I felt fairly qualified
to just dive in and make it markedly better than it was without
getting wrapped around the axle.
