problem with ties

I know that the code for ties and slurs needs a rewrite, but the
positioning should be fine already, shouldn't it?

% . For chords in tight context, ties must occupy horizontal space for
%   themselves.
%   This as a severe bug.
% . The start and end points of ties are not correct in chords with
%   seconds.
%   This is a severe bug.
% . The curvature of small ties is too big.
% . The algorithm to choose the direction of the ties doesn't work
%   properly.  I suggest the following for applying ties sequentially
%   from top to bottom:
%     + The topmost tie is always `up'.
%     + If there is a vertical gap from the current to the last note
%       above larger than or equal to a sixth (or seventh?), the tie
%       is `up', otherwise it is `down'.
%     + The bottommost tie is always `down'.
%   In the last two chords of the example below, the second tie counted
%   from the top should be `down'.
