cross-voice spanners

[Francisco Vila]

Hello all,

I'd like to know what (if any) realistic chances of becoming a part of
the official code base, what is described here

http://lilypondblog.org/2016/08/google-summer-of-code-2016-cross-voice-spanners/

has.

Even a snippet from the page, that is claimed to work "already since
2.18" does not work in my installed 2.19.50.

I mention this because it looks like a dream come true, no other reason.
