[PATCH 0/5] Introduce configs for default repo format

[Patrick Steinhardt <ps@pks.im>]

Hi,

to set up the default object and ref storage formats, users have to set
up some environment variables. This is somewhat unwieldy and not really
in line with how a user typically expects to configure Git, namely by
using the config system. It makes it harder than necessary to globally
default to the different formats and requires the user to munge with
files like `.profile` to persist that setting. Needless to say, this is
a bit of an awkward user experience.

This patch series thus introduces two new configs to set the default
object hash and ref storage format for newly created repositories. Like
this, folks can simply use the global- or system-level config to adapt
to their needs. This also has the advantage of giving them the ability
to adapt the default formats via guarded includes, such that e.g. repos
in some filesystem hierarchy use format A, whereas others use format B.

This comes from a discussion with Sebastian (Cc'd) at the Git User Group
in Berlin yesterday.

Thanks!

Patrick
