[PATCH v5 2/3] pull: move default warning

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

Eventually we want to be able to display the warning only when
fast-forward merges are not possible.

In order to do so, we need to move the default warning up to the point
where we can check if we can fast-forward or not.

Additionally, config_get_rebase() was probably never its true home.

This requires a temporary variable to check if we are in the
"default mode" (no --rebase or --no-rebase specified). But this variable
can be removed later on with further code reorganization.
