Re: Fixes footnote automatic numbering. (issue 4877041)

[pkx166h]

Passes make and make check looks ok, I get something on page
../regression/page-turn-page-breaking.log and I'm attaching the
graphviz.log output (as I don't know if it is significant). But nothing
else pops up.

See http://code.google.com/p/lilypond/issues/detail?id=1791#c5

(ignore the pdf I mistakenly attached if it is still there on the
tracker - I did delete it - the png is the reg test).
