I hope you have realized that \oldaddlyrics is not only deprecated
but actually doesn't work at all! There' no need to keep it, but we
should preferably introduce a convert-ly rule that prints out a warning 
to the user that he manually has to replace \oldaddlyrics
with \lyricsto or the new \addlyrics (which has another syntax).
This was discussed on the mailing list some time ago.

I realize that this breaks Graham's rule that we shouldn't add any
convert-ly rules in 2.12, but the rule should actually be specified
for some old LilyPond version (probably 2.8.x or 2.10.x) where 
\oldaddlyrics actually stopped working. Perhaps this has already been 
done.
