When it checked if a file has the attribute turned on, git-archive would try to look up the full path -- including the prefix -- in .gitattributes. That's wrong, as the prefix doesn't need to have any relation to any existing directories, tracked or not. This patch makes git-archive ignore the prefix when looking up if value of the attribute export-subst for a file. Signed-off-by: Rene Scharfe --- Ulrik, does this patch fix the problem for you?
