Hello!

When I visit large files, for example one with 1,999 or 2,000 MiB  
size, this size is not correctly reported in *Buffer List*:

	.%  Ruhe_1-Paul_Plam: 72943170  Fundamental	  /Volumes/BSD-Linux/ 
Ruhe_1-Paul_Plamper.mp3
	 %  BSD-Linux             1629  Dired by name	  /Volumes/BSD-Linux/

Here are excerpts from dired buffers:

As you can see the 2 GiB TAR file is reported as being 1/6 the size of  
the MP3 file, which actually is approximately 1/30 the size of the TAR  
file.

The buffer of a tar file only contains the table of contents.  The
actual data is stored in a hidden buffer.
