Sorry to be pedantic about variable naming, but stuff in
include/private/svn_*.h is usually prefixed with 'svn__' instead of
'svn_'. Since these private symbols are included in the same library
as the public API, we prefer the naming differentiation so that folks
know these APIs are not for public export or consumption.
