I think maybe the starting point should be to (manually) apply the patch 
on top of that commit in order to check that the bug to leaded to 
pointing that commit as 'first bad commit' is now gone.

Stan has now confirmed this. He applied this patch on top of 4c0104a83fc3, 
and it did indeed resolve the bug that 'git bisect' isolated [1]. Thanks 
Christophe.
