IIRC, you need two more > (owner, perm) or maybe three (group), not 150k. OK that's comforting. The 150k above though is not # of attribute *types* (perms/uid/gid or whatever), it is number of attribute *entries* in a .gitattributes file (eg: /etc/sudoers mode=0440 uid=0 gid=0). Hopefully it shouldn't actually be as high as 150k, i don't know. -JE
