some doc updates

1) talk about "git merge" instead of "git pull ."

2) suggest "git repo-config" instead of directly editing config files

3) echo "URL: blah" > .git/remotes/foo is obsolete and should be
   "git repo-config remote.foo.url blah"

4) support for partial URL prefix has been removed (see commit
   ea560e6d64) so drop mention of it.
