 * sides, regardless of what transformations (svndiff deltification,
 * gzipping, etc) the data may have gone through in between.  
 *
 * The result md5 is always used whenever file contents are
 * transferred, because every transmission has a resulting text.
 *
 * The base md5 is used to verify the base text against which svndiff
 * data is being applied.  Note that even for svndiff transmissions,
 * base verification is not strictly necessary (and may therefore be
 * unimplemented), as any error will be caught by the verification of
 * the final result.  However, if the problem is that the base text is
 * corrupt, the error will be caught earlier if the base md5 is used.
 *
 * Normal WebDAV or DeltaV clients don't use these.
