[PATCH v2 0/2] Show suggested refs when ref unknown

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.

This function can easily be used by other operations involving refs that don't exist instead of providing blanket failure error messages (eg. git checkout foo).

  merge: use help_unknown_ref
