fetch: give a hint to the user when local refs fail to update
There are basically two categories of update failures for local refs: 1. problems outside of git, like disk full, bad permissions, etc. 2. D/F conflicts on tracking branch ref names In either case, there should already have been an error message. In case '1', hopefully enough information has already been given that the user can fix it. In the case of '2', we can hint that the user can clean up their tracking branch area by using 'git remote prune'. Note that we don't actually know _which_ case we have, so the user will receive the hint in case 1, as well. In this case the suggestion won't do any good, but hopefully the user is smart enough to figure out that it's just a hint.
