uuencoded attachments produce woe

[Greg Louis]

Gary Robinson had occasion to send me a .pdf file recently; it arrived
uuencoded, and was deemed spam by bogofilter; the training had only seen
uuencoded attachments in spam before.  Running bogofilter with the -R
option showed about 7,000 unhelpful tokens had been generated.

Reading the comments in lexer.l, it seems that BASE64 is being avoided,
but not uuencoding.  I have no idea whether it would be hard or easy to
change that; anyone care to comment?
