Aha.  Much the same purpose as my stripovr, last revised in '98 to
handle those escape sequences in man listings.

c:\dnld\scratch>stripovr
STRIPOVR copyright (c) 1998 by C.B. Falconer.  Ver 1.4

usage: STRIPOVR [/1e] <infile >outfile
Removes all overprinting lines,
i.e. lines that end in a cr without a following lf
     and ch <backspace> ch sequences (uses last ch).
     and ANSI escape sequences (ESC[...ch) ch alphabetic

The LAST line in an overprinting group is retained.

The optional /1 parameter causes the FIRST line in an
overprinting group to be retained, while the e (or E)
modifier causes ANSI escape sequences to be stripped.

The / may be replaced by a - in the options

Input lines may not exceed 255 chars.

Omitting "<infile" causes this help screen

c:\dnld\scratch>

So the answer to the OP's question is 'yes', since stripovr runs
under DOS.  Send me an email and I can attach it in a reply.  It
is a monstrous 10k bytes.
