Minor suggestion for

[Anthony Cartmell]

Try as I might to sort out whitespace differences, I always get some  
appearing in my diff after upgrade_MailScanner_conf.

Might it be an idea if upgrade_MailScanner_conf suggested using diff with  
"-w", to ignore whitespace changes?

diff -w MailScanner.conf.rpmnew MailScanner.new

Perhaps that's not platform-independant enough...
