If (like me) you have neither ``plain'' nor ``pep'', (I'd expect the latter
to be a comms package from Telebit!), don't despair.

You can use the filter "col -b" to do just this:
	1G!Gcol -b
works fine from within vi, for example.

Deleting control-h and _ in vi is also easy, of course:
	:%s/[^H_]//g
(you have to type control-V control-H tp get the ^H in there, of course)
