Use single function to calculate of text lines and columns
because algorithm is the same for all encodings.

Suppose we have 3 files with version in their names:
* file-2.1.tgz
* file-2.2.tgz
* file-2.10.tgz
It is impossible to see them in natural order using standard facilities,
they will be sorted in alphabet order:
* file-2.1.tgz
* file-2.10.tgz
* file-2.2.tgz
There was some attempts to fix this. I've picked up the patch by Roland Illig <roland illig gmx de>
(http://mail.gnome.org/archives/mc-devel/2004-July/msg00016.html) and adopted it for today's git snapshot.
It adds "version" option to the sort menu, which uses copy of strverscmp function from glibc.
