Enhancement request: Automatic glissando marks in chords

[Patrick Schmidt]

Dear developers,

as I quite often engrave Rock Riffs I discovered that it is  
comparatively complicated to typeset chord slides (using hidden  
voices and spacer notes). From my point of view it would be more  
intuitive if it were possible to set glissandi in chords just the way  
ties are set, e.g.: <c e g>\glissando<d fis a>
resulting in one glissando mark for each voice in chords. But this is  
probably hard to implement ...

Thank you all for this brilliant software and beautiful printouts!
