[PATCH 0/2] Better advice on merge

If origin/foo exists, but foo doesn't:

   $ git merge foo
   fatal: foo - not something we can merge

This patch series improves the error message. If a remote branch exists with the same name, it now says:

     $ git merge foo
     fatal: foo - not something we can merge

     Did you mean this?
     	 origin/foo

It does this by adding a new help function, help_unknown_ref, that takes care of printing the more friendly error message, and modifies builtin/merge.c to use it. In the future, this could also be extended to other operations involving branches that don't exist locally, instead of providing blanket failure error messages (eg. git checkout foo).

  help: add help_unknown_ref
  merge: use help_unknown_ref instead of die
