 %************************* liaisons horizontales **************************
 % Tie Fixes.
 % I have rewritten several tie macros to eliminate those annoying gaps which
 % often appear. The new macros cause ties to be extended with leader, rather
 % than lines whose length has to be guessed. TeX cannot make multiple
 % horizontal lines with \leaders, so instead I use an \hbox containing
 % several short fragments of lines. Each line fragment is of length
 % \tenboxwidth, which is initially .75pt.
 % In order for the new ties to work properly, every horizontal space must be
 % recorded. I have had to amend some macros so that they record the space
 % which they produce.
