Actually, all 3 work as expected -- the TrillSpanner stops, and a new
TrillSpanner is created.

What you have found is that under some conditions there is a collision
between consecutive TrillSpanners.  I'd suggest that this is a collision
bug, rather than a bug with the TrillSpanner stopping.  And it's probably
caused by the character used to create the spanner having a bounding box
slightly smaller than its ink extent, which allows the characters to stack
nicely without white space between.  (see comment #7 on issue 881
<http://code.google.com/p/lilypond/issues/detail?id=881> for a description
of how this affected arpeggio collisions with ties)
