I do not have objections, but it feels that the message for normal case
(success) is cluttering the output.

If the remote repository is in a bad shape to solicit a "points nowhere"
error, perhaps

 (1) that error message should be squelched out completely, as it does not
     affect the outcome of the fetch anyway, or

 (2) the dangling symref should cause "fetch" to error out but with a
     different error status than the total failure case, so that this
     caller can tell it is a non-grave error, or

 (3) the dangling symref should actually make the fetch fail, as the
     remote repository is corrupt.

For now I'll take your patch, but this is something we may want to
clean-up in 1.6.0 timeframe.
