fwiw, I think enabling it by default especially when that really means
enable it if you've enabled the localrc plugin makes sense.  I don't see
how you can enable the localrc plugin and then complain when people use
it for its designed purpose.  However something in contrib/ is probably
easier for new people to find than something on the wiki or something so
better than doing nothing :)

Thanks!
