[PATCH v2 18/19] pull --rebase: error on no merge candidate cases

[Paul Tan <pyokagan@gmail.com>]

Tweak the error messages printed by die_no_merge_candidates() to take
into account that we may be "rebasing against" rather than "merging
with".

Notes:
    v2
    
    * Decided to use fprintf_ln() for the sake of code consistency, and for
      the added trailing newline.
