Summary: problems with \letterspacefont

Initial Comment:
% Testing the new \letterspacefont, I found:
%
% (1) it's certainly not correct to have the spacing 
%     relative to character widths (look at `minimal'!)
% (2) everything's shifted to the right
% (3) when trying to expand the letter-spaced font, I 
%     get the warning `font should be expanded before 
%     its first use' (even before its first use), and 
%     then pdftex segfaults.

% and here's
% (4) ligatures will be broken up, not only in the 
%     letter-spaced font (which is probably acceptable), 
%     but in all subsequent uses of the base font, too

I fixed (1) and (2); (3) is disabled now, ie you cannot
expand a letter-spaced font. Please wait for another release
from Martin.
