[PATCH] Explicitly add the default "git pull" behaviour to .git/config on clone

[Andy Parkins <andyparkins@gmail.com>]

Without any specification in the .git/config file, git-pull will execute
"git-pull origin"; which in turn defaults to pull from the first "pull"
definition for the remote, "origin".

This is a difficult set of defaults to track for a new user, and it's
difficult to see what tells git to do this (especially when it is
actually hard-coded behaviour).  To ameliorate this slightly, this patch
explicitly specifies the default behaviour during a clone using the
"branch" section of the config.

For example, a clone of a typical repository would create a .git/config
containing:
  [remote "origin"]
  url = proto://host/repo.git
  fetch = refs/heads/master:refs/remotes/origin/master
  [branch "master"]
  remote = origin
  merge = refs/heads/master

The [branch "master"] section is such that there is no change to the
functionality of git-pull, but that functionality is now explicitly
documented.

This is really to help newbies.  By explicitly documenting the default
behaviour, it makes it clearer what is going on.  It also means no routing
through documentation to find out what config option needs changing.

It's possible that we would want to remove the default behaviour entirely
if there is no "branch" definition in the config.  That would prevent
accidents by users who don't know what pull does fully yet.
