Re: multi-wc-format branch ready for initial review

Brane, do I correctly understand the impact of this branch could be
summarized as "API support to enable a future version of the client
software to support multiple WC versions":

   * Enables future client software to detect, create, use without
upgrading, and optionally upgrade any WC version in the supported range.

   * The supported range is initially just the current WC version; this
does not add a new WC version to the supported range.

   * To actually support multiple WC versions, the client software will
need explicit cases for each supported WC version in the handling of
each feature that varies across versions.

That seems to match the branch description at

http://svn.apache.org/repos/asf/subversion/branches/multi-wc-format/BRANCH-README

Thinking again, we need an implementation of multiple WC versions to
test it. It would be wise not to merge until we have tested with such an
implementation.

What is the most feasible way forward with this? Is the
'better-pristines' branch anywhere near providing at least "dummy"
handling of a new WC format, sufficient to test these support APIs, even
if it is not yet actually implementing better-pristines?
