Well, can someone please install the changes? 
If more clarifications are needed, just ask. 

ediff-init.el and compare-w.el have also been converted to use
min-colors (also diff-mode.el, that change has already been installed). 

Eli, in case you are watching this, for ediff-init.el the places where
(class pc) were treated differently than (class tty) have been kept, I
can guess it was done that way because ":weight bold" was not
desirable for (class pc). 

Thanks.
