/*

  Fixes a directroy name so that can be used by open()



  SYNOPSIS

    unpack_dirname()

    to			result-buffer, FN_REFLEN characters. may be == from

    from		'Packed' directory name (may contain ~)

/**

  Convert a directory name to a format which can be compared as strings



 IMPLEMENTATION

  Make that last char of to is '/' if from not empty and

  from doesn't end in FN_DEVCHAR

  Uses cleanup_dirname and changes ~/.. to home_dir/..

  @param to     result buffer, FN_REFLEN chars in length; may be == from

  @param from   'packed' directory name, in whatever format

  @returns      size of the normalized name



  Changes a UNIX filename to system filename (replaces / with \ on windows)

  @details

  - Ensures that last char is FN_LIBCHAR, unless it is FN_DEVCHAR

  - Uses cleanup_dirname



  RETURN

   Length of new directory name (= length of to)

  It does *not* expand ~/ (although, see cleanup_dirname).  Nor does it do

  any case folding.  All case-insensitive normalization should be done by

  the caller.
