Using casefolded wordlists

[Peter Bishop]

There may be an upgrade problem to 0.13 for those of us who don't maintain 
a spam archive.

If I use the old casefolded wordlist it clearly will not recognise mixed 
case words like FREE OFFER. Ditto for ham email, there will be  more 
unrecognised words.

For example:

email   spamicity (robinson)
ham   0.35 (Pi)     0.47 (PI)
ham2 0.37 (Pi)     0.47 (PI)
spam 0.62 (Pi)     0.63 (PI)
spam2 0.61(Pi)    0.61 (PI)

>From my unscientific sample it appears that ham is affected more than spam 
and the effect could be to increase false positives until the wordlists get 
updated with mixed case words
