Function remote_tracking

remote.c:2679–2694

* Look at remote.fetch refspec and see if we have a remote * tracking branch for the refname there. Fill the name of * the remote-tracking branch in *dst_refname, and the name * of the commit object at its tip in oid[]. * If we cannot do so, return negative to signal an error. */

 * If we cannot do so, return negative to signal an error.
