FWIW, I found it very confusing. I would have expected "diff.options" or

useful model.

OK, point taken.  I wasn't trying to be idiosyncratic at all.  Just trying to be 
explicit and avoid all confusion.  Since all diff options already have default 
values, primer looks to me like the layer one step above defaults, hence the 
painting analogy.  Mercurial calls it "defaults", but that doesn't mean we 
should necessarily follow in their footsteps (see 
http://article.gmane.org/gmane.comp.version-control.git/107103).

I think being as clear as possible about what primer is, that is it NOT 
defaults, helps to feel more comfortable with its consequences, i.e. in my 
opinion, that it will not break things.
