I have strong reservations about the ignore-invisible-text change,

  r9460 | jm | 2004-03-13 23:49:08 -0600 (Sat, 13 Mar 2004) | 1 line

A message could be crafted so that it would be considered not
"visible_for_bayes" but still visible enough when using an email
client.  That might be done by using a seemingly low contrast color
pair or by markup that tricks the code into thinking the text is
invisible (for example, using complex styles).

Such messages would get around one of the most robust spam detection
techniques.  

As an alternative, tag invisible text, as suggested in Comment 10.

I'd be happy to make the changes if others are too busy.
