Set document metadata failed

'cpoptions' option.

Note that the 'fsync' option matters here.  If it's set it may make writes
slower (but safer).

                                                        :sav :saveas
:sav[eas][!] [++opt] {file}
                        Save the current buffer under the name {file} and set
                        the filename of the current buffer to {file}.  The
                        previous name is used for the alternate file name.
                        The [!] is needed to overwrite an existing file.
                        When 'filetype' is empty filetype detection is done
                        with the new name, before the file is written.
                        When the write was successful 'readonly' is reset.
                        {not in Vi}

                                                        :up :update
:[range]up[date][!] [++opt] [>>] [file]
                        Like ":write", but only write when the buffer has been
                        modified.  {not in Vi}

保存當(dāng)前緩沖器的名稱(chēng)&文件
                                                         用文件名 {file} 保存當(dāng)前緩沖區(qū)，并設(shè)置當(dāng)前緩沖區(qū)的文件名為 {file}。 
                                                         前一個(gè)名字用作輪換文件名。 
                                                         [!] 用以覆蓋已存在的文件。 
                                                         如果 'filetype' 為空，在寫(xiě)入文件前用新名字進(jìn)行文件類(lèi)型檢測(cè)。 
                                                         如果寫(xiě)操作成功，復(fù)位 'readonly'。
