Won't work.  Think what happens on "abc^H^H^H".

I wasn't going to post a sed solution because it looked to be messy, but
it would need to be something like

    sed ':top
	/.^H/{
	s///
	b top
    }'

or, a little more efficiently, if there are multiple ^H fields,

    sed ':top
	/[^^H]^H/{
	s///g
	b top
    }'

You ought to be able to use

    sed ':top
	s/[^^H]^H//g
	t top'

but t is buggy some locales.
