Syntax:  RECOVER BUFFER file_spec

  Reconstructs the contents of a buffer from a buffer-change journal
  file.

  You can specify either of the following files:  the source file that
  was in the buffer or the full name of the buffer-change journal file.

  The RECOVER BUFFER command tries to rebuild the contents of a buffer
  by using the latest available generation of the file that was in the
  buffer, and a journal file that contains a description of the changes
  to that buffer.

  Before LSE tries to recover a buffer, information about the journal
  file is displayed.  When you specify an asterisk (*), LSE displays
  information about each available journal file in succession.  You can
  choose not to recover a buffer if the information describes a journal
  file other than the one you want.

  For example, this command recovers the buffer message.txt:

                LSE>  RECOVER BUFFER message.txt
