Hmm, thats annoying. Almost makes me wish it was the trees that were signed, not the commits. Although, I probably could brew up a prototype resigning tool ( based on Git::PurePerl ,... when they accept and publish my changes ) , just would be problematic because simply the act of signing a past commit means the SHA1 of the commit itself is different, so all successive commits after a re-signed commit will change and also need to be rebased and re-signed. -- Kent perl -e  "print substr( \"edrgmaM  SPA NOcomil.ic\\@tfrken\", \$_ * 3, 3 ) for ( 9,8,0,7,1,6,5,4,3,2 );"
