Re: "Closed" fret diagrams

[Valentin Petzel]

Hello Werner, hello Bophead,

this is actually very trivial to tweak. It requires an adaptation of a single 
line and maybe some mechanism of specification. The appended file modifies the 
relevant code in such a way that fret-diagram-details.extra-string-length can 
be used to specify the extended string length in fret distances (1 for a 
single fret space). All that is required is a minor change in one line for 
printing and two added lines for scoping the parameter.

The appended file is intended for demonstration and a little bit naughty and 
should probably not be used extensively.

Cheers,
Valentin
