Markup snippet breaking docs (\rotate)

[Neil Puttock]

Hi everybody,

I've inserted this perfectly innocent looking snippet into
define-markup-commands.scm,

@lilypond[verbatim,quote]
\\markup \\rotate #180 { foo }
@end lilypond

which causes a failure in docs compilation. Here's the relevant error info:

/home/neil/lilypond/out/share/lilypond/current/scm/framework-eps.scm:42:10:
In procedure ly_make_stencil in expression (ly:make-stencil
(ly:stencil-expr stil) (cons left #) ...):
/home/neil/lilypond/out/share/lilypond/current/scm/framework-eps.scm:42:10:
Wrong type argument in position 1 (expecting registered stencil
expression): (rotate-stencil (180.0 (1.4340188976378 .
0.802367716535433)) (combine-stencil (translate-stencil (0.0 . 0.0)
(glyph-string "CenturySchL-Roma" 3.865234375 #f (quote
((0.682866141732283 0.0 0.0 "f") (1.09258582677165 0.0 0.0 "o")
(1.09258582677165 0.0 0.0 "o"))))) ()))

The following snippet works fine:

@lilypond[verbatim,quote]
\\markup { foo \\rotate #180 bar }
@end lilypond

Any idea what's going wrong?

Regards,
Neil
