Ties within chords inconsistency

[Simon Albrecht]

Hello,

consider the following example:
%%%%%%%%%%%%
\version "2.19.25"

\new Voice << { c''^~ c'' } { a'_~ a' } >>

\new Voice << { <c''^~> c'' } { <a'_~> a' } >>

{ <c''^~ a'_~> <c'' a'> }
%%%%%%%%%%%%

Contrary to (at least my) expectation the first example gives

tie-within-chord.ly:6:33 <0>: warning: Two simultaneous tie events, 
junking this one

\new Voice << { c''^~ c'' } { a'

_~ a' } >>

and applies the first tie to both notes.
The other two give correct output, and it would serve consistency and 
predictability if the first did also.

Possibly related: <http://sourceforge.net/p/testlilyissues/issues/2240/>.

Yours, Simon
