Sorry, this is not a proper reply to my previous mail. I just subscribed to the list.
I want to add this patch was a replacement for an earlier one. See
[PATCH] Add two core.sharedRepository options: group-readable and world-readable http://marc.info/?l=git&m=120792433430899&w=2 and [PATCH] Add core.sharedRepository == read-only-group http://marc.info/?l=git&m=120777054707525&w=2
'read-only-group' was renamed to 'group-readable', and 'world-readable' option was added, as per comments of Bjorn Steinbrick.
