few questions on minor errors in LM and website

[Federico Bruni]

1) A small error in Documentationo/learning/tweaks.itely:

@node The force-hshift property

@unnumberedsubsubsec The @code{force-hshift property}

It should be:

The @code{force-hshift} property

2) http://www.lilypond.org/productions.html

A critical edition of Tommaso Traetta’s Enea nel Lazio (1760), opera series with libretto by Vittorio Amedeo Cigna-Santi, in four parts: Part OnePart Two Part Three Part Four Created by Luca Rossetto Casel for his Ph.D. Thesis.

Opera series? Or opera seria?

I'm very ignorant in classical music, but series doesn't make sense to me and I found this:

Thanks
