## Beaming rules may cause oddness when using hideNotes

Greetings everybody,

I've just stumbled upon the following piece of code, and it took me a
while to understand what was going wrong (although, granted, I should
know better).

\new Staff <<
\new Voice { \voiceOne
\set tieWaitForNote = ##t
c''16~ b''~ <c'' b''>8~ b''2.
}
\new Voice { \voiceTwo
s8
\hideNotes
c''~
\unHideNotes
c''8. d''16 c''2
}
>>

Printed scores usually use 2+2 beaming for 4/4 time signatures, but
they revert to 4+4+4+4 whenever there's a silence or a trick such as
the one above. In this particular case, the (attached) output is
clearly not something one would expect to happen by default; that
being said, I'm not sure the beaming rules can be made more
intelligent (see #638, for example). Perhaps it's just something to
document? (Or maybe that's just me ;)

Thanks!

Valentin.
