// Created <client-side-dir>/
// <server-side-dir>/<filename>
// /<filename>/<version>///
// <file-mode>
// <length>
// <length-bytes-of-contents>
//
// This is just like Updated and takes the same additional data, but
// is used only if no Entry, Modified, or Unchanged request has been
// sent for the file in question.
//
// The distinction between Created and Update-existing is so that the
// client can give an error message in several cases:
// (1) there is a file in the working directory, but not one for which
//     Entry, Modified, or Unchanged was sent (for example, a file which
//     was ignored, or a file for which Questionable was sent),
// (2) there is a file in the working directory whose name differs
//     from the one mentioned in Created in ways that the client is
//     unable to use to distinguish files.  For example, the client is
//     case-insensitive and the names differ only in case.
//
//
// The output looks something like this...
//
