Again: Default size of filesize?

[Alexander Oberhuber <lzw77rnc gmx at>]

Okay,

Someone did not understand my last question.
Let me rephrase:
When I use MC, how do I change the default numbers-of-characters that 
are being used for displaying the "filesize"-column?
As standard, the filesize is displayed 7 characters wide (if I have 
counted it correctly).
Where do I change the default length of the filesize column, 
preferably for both tabs?
