I have the following code for use with headers which might not be defined for
some pieces:
#(define-markup-command (when-property layout props symbol markp) (symbol?
markup?)
(if (chain-assoc-get symbol props)
(interpret-markup layout props markp)
empty-stencil))
Then in the header definition I can put something like:
\when-property #'header:poet \concat { "Lyrics: " \override #'(line-width .
26) \wordwrapleft-field #'header:poet }
