Re: Mismatched backwards compat callbacks in libsvn_wc

A much simpler way to accomplish the same goal is to stop the bizarre
new trend of, every time svn_api_foo2 is implemented, instantly
"upgrading" every call to svn_api_foo to use svn_api_foo2 instead.
Leaving the old calls in (except for cases where the caller really
does need to use the new functionality) means that our own codebase
will automatically test the backwards-compatibility code. Plus, this
would mean doing less work and reduce pointless code churn that makes
merges more difficult.
