does the X-Bogosity line mess up spamicity calculations?

hmph.

I'm not able to reproduce any output from the above instructions. I am *VERY* 
inexperienced with linux in general so bear with me.

1) Should there be a double greater than on line 4 so we append instead of 
overwrite?
# echo "" > $s

2) bogofilter doesn't do anything with the last line given except generate an 
error:
Extra arguments given, first: /tmp/mail.txt. Aborting.
Perhaps it should be:

bogofilter -l -vvv < $s

3) this generates a report, shows that it's not spam, but I don't see anything 
that illuminates anything about how it processes or doesn't process the 
X-Bogosity line:

X-Bogosity: No, tests=bogofilter, spamicity=0.520000, version=0.92.2
