Ok, thanks. If I do that, one thing I can't figure out from the 
documentation is how to indicate a barre if I'm using an automatic fret 
diagram. For example, If I replace

<<
    \context ChordNames {
        \chordmode {
            a1
        }
    }
    \context Staff {
        \clef "treble_8"
<a, e a cis' a'>1^\markup {
            \fret-diagram #"c:4-1-2;6-x;5-o;4-2-1;3-2-1;2-2-1;1-5-4;" }
    }
>>

where the barre is specified with c:4-1-2, and use instead

<<
    \context ChordNames {
        \chordmode {
            a1
        }
    }
    \context FretBoards {
<a, e a cis' a'>
    }
    \context Staff {
        \clef "treble_8"
<a, e a cis' a'>
    }
>>

Then how do I indicate the barre in the FretBoards context?
