Subversion has a number of configuration files which are consulted by clients
and servers of all version pedigrees. The runtime configuration files
(~/.subversion et al), svnserve config files, and so on. As we add new options
to these files, we should be noting which Subversion versions will honor those
options.
It is not unreasonable to think that my runtime configuration area could have
been created by a Subversion 1.7 client, but that from time to time I need to
use a 1.6 client on the same machine. Users in such situations might be
confused as to why, when they modify a new-in-1.7 config option (in the file, or
via the --config-option switch), it seems to have no effect on their 1.6
client's behavior.
