What I want to avoid is the code getting into a halfway state, where we
have machinery for a feature we never wind up coding.

Replacing the keyword structure with a hash, and doing nothing else,
seems like a nice way of making the keyword mechanism more generic--or
it would, except that the API of svn_subst_build_keywords seems
dependent on what kind of information goes into keyword processing.

Adding a printf framework, on the other hand, is just a waste of code if
we never wind up adding a feature that would let us do FreeBSD --> "%b
%D %a %r" or whatever. So, in the absence of a spec and design for such
a feature, I don't want to see the printf framework code going into our

Also, a note on properties-as-keywords: the patch you sent to the list
(http://www.contactor.se/~dast/svn/archive-2004-04/1184.shtml) does not
appear to re-substitute files after an "svn propset". Without that
code, the working copy can easily get into an inconsistent state, and I
don't think that's acceptable. (Of course, any code to re-substitute
files after propset would have to be careful not to impose a great cost
on propset operations for files which have no property keywords.)
