[PATCH] alternate object store and fsck

The location alt_odb[j].name[0..] is filled with ??/?{38} to form a sha1
filename to try, but I was too lazy to allocate a copy, so while
fsck_object_dir() is running for the directory, the filenames ??/?{38}
are filled after NUL (usually and always the location should have '/'),
making them "not found".

This should fix it.
