  Exactly, you have to do that. And only the owner can change the modes,
thus, unless all users have their umask set up right, someone gets toasted.
  Since the directories are created on the fly, they need to be created
with the right permissions.

  Never heard of "git-init-db --shared".

A shared repository allows users belonging to the same group to push
into that repository. When specifying `--shared` the config variable
"core.sharedRepository" is set to 'true' so that directories under
`$GIT_DIR` are made group writable (and g+sx, since the git group may
be not the primary group of all users). 

  That would seem to be the right thing.
  Seems it was added in December.
