> I think this branch is now ready to merge to trunk.
I am now asking for review.
To help, here is an overview of the branch changes, compiled from its
log messages:
------------------------------------------------------------------------
Instead of supporting just one format, introduce a current format
(the default for new working copies) and a lowest supported format.
Change the way new working copies are created: instead of the base
schema defining the current format, it defines the lowest supporting
format and a series of format updates are performed to bring it to the
current shape.
Add the --compatible-version option to the checkout and upgrade
commands.
Guess the format of dependent working copies (e.g., for externals) from
the current working copy context.
Add a line to the 'svn --version' output that shows supported WC versions.
Include a place-holder format bump. This makes it easier to merge with a
branch that includes a format bump (such as the 'pristines-on-demand'
branch).
Add test suite option '--wc-format-version'. This accepts a version
string like '1.14.0' and is used for all WC creation, e.g. 'svn
checkout/upgrade --compatible-version=X'.
