Although the exact parameters may not be admin-configurable, will they
still be Subversion-configurable? That is, will we store the magic
number "4000" somewhere on disk, so that if Subversion wants to
rejigger the numbers later (because we discover something, or because
someone blows past 16M revisions, or whatever) it can do so in a way
that it can detect at run-time?
