[PATCH v14 0/2] checkout: --track=fetch

Extend checkout --track with a fetch mode to refresh start-point.

Changes in v14:

 * Handle .h files in a better way.

Changes in v13:

 * Create a preparatory commit that exposes find_tracking_remote_for_ref()
   and advise_ambiguous_fetch_refspec() from branch.c, so checkout can reuse
   the same lookup git branch --track uses.
 * Use advise_ambiguous_fetch_refspec() for the "multiple remotes match"
   case, so the wording matches git branch --track.

Harald Nordgren (2):
  branch: expose helpers for finding the remote owning a tracking ref
  checkout: extend --track with a "fetch" mode to refresh start-point
