It could be that 4d0d8975 is buggy and barking at a non breakage.

If there is no message in the tag, i.e.

    -- 8< --
    object 84ef51a632063e8cb57b2e9a4252497512831ffe
    type commit
    tag LABEL_2006_03_12_0025
    tagger Wolfgang Denk <[email-masked]> 1142119613 +0100
    -- >8 --

I do not offhand see why we want to require that there is a lone
blank line at the end.

Dscho?  What do you think?
