SVN_WC__WC_NG_VERSION is declared in wc.h, which this file isn't allowed
to use.
Why does this function special-case f12 over all other format numbers
only created by unreleased trunk revisions? Why is f12 handled
differently to f6, f11, f13, f25, and f30? It seems to me we should
either return NULL for all of them, or return the appropriate
svn_version_t value for each of them (and for all other integers between
11 and 28), as needed.

The trailing comma is not C89-compatible and used to break the Windows
build.
