Since attr checking API now take the index, there's no need to set an index in advance with this call. Most call sites are straightforward because they either pass the_index or NULL (which defaults back to the_index previously). There's only one suspicious call site in unpack-trees.c where it sets a different index. This code in unpack-trees is about to check out entries from the new/temporary index after merging is done in it. The attributes will be used by entry.c code to do crlf conversion if needed. entry.c now respects struct checkout's istate field, and this field is correctly set in unpack-trees.c, there should be no regression from this change.
