problem or bug?

To whom it may concern,
Hi, I have some problems here with Lilypond 2.6.3. I've attached both 
example.ly and example.pdf for your reference.
In the 2nd bar, why is the appoggiatura slur not attached to the note heads 
of both the appoggiatura and the main note? Instead, as shown, the slur is 
at the end of the stem.
In the 5th bar, I'm puzzled as to why the running trill line does not span 
to the end of the bar when I explicitly attached the \stopTrillSpan at the 
last spacer quarter note of the bar? I could "cheat" by attaching 
\stopTrillSpan to a hidden grace note at the end of the bar but I wouldn't 
like to do this everytime.
Can both these problems be rectified or are they bugs of version 2.6.3?
Thank you.
Yours sincerely,
Seng Liang.
