As far as I can see with my limited guitar knowledge this solution
suffers, in the case of hold lines extending over line breaks, from a)
the ending vertical line being applied before the line break and b) the
string number/number of strings indications being repeated after the
line break.

which is the case with the version of \holdc used with the guitar
accompaniment version of my Aakj�r songs recently published.
