Developers FAQ updated with this macro.

OK.  I just know some developers added them on their own, so it
certainly is an issue for them.

Also, is there a way to add a dot-file in a directory to control default
formatting, but still allow the main .emacs to be read?  .exrc is used
for vi and it controls formatting for all files edited in that
directory.
