Hi Oliver,

Thanks for your time.  Here's an example of html2text's output, displayed in an 
Emacs buffer:

Here is how it looks on a tty or in an Emacs *shell* buffer:

I had thought that they might be remnants of HTML tags, (I must admit I didn't 
look very closely), but I have found out since they are actually ANSI 'backspace 
control sequences', used to preserve things like underlining and boldface.  The 
html2text option '-nobs' gets rid of them.

(After days spent looking for information, I discovered that html2text comes 
with a manpage and all was revealed.  DOH!)
