Documentation: update git-pull.txt for new clone behavior

Update examples, stop using branch named "origin" as an example.
Remove large example of use of remotes; that particular case is
nicely automated by default, so it's not so pressing to explain, and
we can refer to git-repo-config for the details.

-Here, a typical `.git/remotes/origin` file from a
-`git-clone` operation is used in combination with
-command line options to `git-fetch` to first update
-multiple branches of the local repository and then
-to merge the remote `origin` branch into the local
-`master` branch.  The local `pu` branch is updated
-even if it does not result in a fast forward update.
-Here, the pull can obtain its objects from the local
-repository using `.`, as the previous `git-fetch` is
-known to have already obtained and made available
-all the necessary objects.

-Pull of multiple branches from one repository using `.git/remotes` file::
+This updates (or creates, as necessary) branches `pu` and `tmp`

+(respectively) `pu` and `maint` from the remote repository.
