First, please go look at the git-config manpage to see how much more is
needed to have anything even close to letting us say "you don't need to
poke in .hg/hgrc". And then consider how much harder to use and how much
more documentation you have to read to do anything non-trivial and how
much more fragile all that stuff is than simply saying "<editor of
choice> .hg/hgrc".

Your claim that we shouldn't have editable files in .hg, well that's
never been the case and people have never really complained about
accidentally editing their dirstate, so I think that's a non-issue. 

(The related idea that using your editor on a text file is hard for
people using an SCM is just ridiculous. Please, folks, don't bring it up
or I will be forced to ridicule it.)
