Open strings in chords (commit 9203eadca5bcb79415060f8488889706a9c8e62a)

[Marc Hohl]

Hello all,

while typesetting a piece for two guitars, I stumbled across
the influence of the commit mentioned above.

Before that,

something like

\set minimumFret = #2
dis'8 ( e' dis ) h fis2

worked smoothly out of the box, now I have to tell
lilypond explicitly which string to use when I want to
avoid open strings.

\set minimumFret = #2
dis'8 ( e\2 dis ) h\3 fis2 |

I dont want to make lilypond input even more complicated,
but what about a separate switch, something like

\tabOpenStringsOn \tabOpenStringsOff ?

These commands control whether open strings
are taken into account or not.

Perhaps I have some time to create a patch myself
within the next week or so.

Regards,
Marc
