Hello,
Thank you very much for the great work you are doing with lilypond!
I noticed that when you create more than 9 footnotes in the same page with
the markup command named \auto-footnote, the delayed stencil used for
writing the number has incorrect size.
This is an example to reproduce the bug :
\version "2.18.0"
\markuplist {
\line { \auto-footnote one { one } \auto-footnote two { two } }
\auto-footnote three { three }
\line { \auto-footnote four { four } \auto-footnote five { five } }
\line { \auto-footnote six { six } \auto-footnote seven { seven } }
\auto-footnote eight { eight }
\line { \auto-footnote nine { nine } \auto-footnote ten { ten } }
\line { \auto-footnote eleven { eleven } \auto-footnote twelve { twelve } }
}
