  It seemed that this was needed for OS/2, in which \v(cmdfile) and other

  directory separators (e.g. see commented section for VN_CMDF below).
  But the problem can't be cured at this level.  Example:

    type \v(cmdfile)

  Without doubling, the filename is parsed correctly, but then when passed
  to UNIX 'cat' through the shell, the backslash is removed, and then cat
  can't open the file.  With doubling, the filename is not parsed correctly
  and the TYPE command fails immediately with a "file not found" error.

  X X S T R I N G  --  Expand variables and backslash codes.

  Argument s2 is the address of where to put result (destination).
  Argument n is the length of the destination string (to prevent overruns).
  Returns -1 on failure, 0 on success,
