diff: replace --merge option by config option
I can't think of any reason you'd want to enable the merge diff on a
run-to-run basis; you'd probably either always or never want it set
(though I can't see why you'd never want it set). If you have it set,
you'll probably also want the same output in `hg log -p`
output. Having a single config option for the feature makes sense.

Tag:
$ hg tag 1.0
Rewrite .hgtags file as it would look on a new checkout:
$ hg update -q null
$ hg update -q
Touch .hgtags file again:
$ hg tag 2.0
$ cd ..
