When I do: git -c fetch.fsckObjects=true clone git@xxxxxxxxxx:robbyrussell/oh-my-zsh.git I get: error: object 2b7227859263b6aabcc28355b0b994995b7148b6: zeroPaddedFilemode: contains zero-padded file modes fatal: Error in object fatal: index-pack failed The docs (https://git-scm.com/docs/git-config#git-config-fsckltmsg-idgt) say you can override this with -c fsck.zeroPaddedFilemode = ignore, but I see in builtin/fsck.c that just fsck_config() knows about this, and indeed this works *after* you clone the repo when you use 'git fsck'. I don't have time to fix this now, but what's the best approach here? Make all the relevant commands copy what fsck_config() is doing, or should fsck_object() be lazily looking up this config by itself?
