it starts to use 2 levels (even if annex.tune.objecthash1=true) of hash directories having 3 characters in the filename at each level. So it is not just \"taken existing hash directories (1 or 2 levels) and use their lower-case version. It is a different way to create the hash directories:
e.g. one with objecthas1=true
1 -> .git/annex/objects/qj/SHA256E-s6--ecdc5536f73bdae8816f0ea40726ef5e9b810d914493075903bb90623d97b1d8/SHA256E-s6--ecdc5536f73bdae8816f0ea40726ef5e9b810d914493075903bb90623d97b1d8
and if I provide all three options at once:
1 -> .git/annex/objects/ccf/a40/SHA256E-s6--ecdc5536f73bdae8816f0ea40726ef5e9b810d914493075903bb90623d97b1d8/SHA256E-s6--ecdc5536f73bdae8816f0ea40726ef5e9b810d914493075903bb90623d97b1d8
