[PATCH v3 02/16] pull: improve default warning

[Felipe Contreras <felipe.contreras@gmail.com>]

We want to:

1. Be clear about what "specifying" means; merge, rebase, or
   fast-forward.
2. Mention a direct shortcut for people that just want to get on with
   their lives: git pull --no-rebase.
3. Have a quick reference for users to understand what this
   "fast-forward" business means.

This patch does all three.

Thanks to the previous patch now "git pull --help" explains what a
fast-forward is, and a further patch changes --no-rebase to --merge so
it's actually user friendly.
