As in the previous case these messages are already valid utf-8 text, and
thus, if output on a byte-by-byte basis, must not use WriteChar, except
for the EOL char.
Of course this output can be to either a user ouput file, if configured,
otherwise stderr.
This is a MUCH SANER approach to what I was trying to do (now that I screwed up enough internals to understand some of them!
At this point there are zero exit state reversions, and zero markup reversions! There are still 21 errout reversions; I'll
annotate and adjust as necessary.
