problem or bug?

seng_liang
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.

The appogiatura slur placement is probably a bug, but
it is easy to fix by overriding 'positions:

\override Voice.Slur #'positions = #'(0 . 0)

In fact this is what I do every time.  Is it so much
trouble?  You can also attach the \stopTrillSpan to a
rest and hide that, eg.

\once \override Rest #'transparent = ##t
r8\stopTrillSpan

Cheers,

Doesn't it work with a spacer note, s8, so you don't have to fiddle with
making things transparent?

In my experience attaching \stopTrillSpan to a spacer
note produces less than optimal results, for example:

a\startTrillSpan a a\stopTrillSpan
a\startTrillSpan a s\stopTrillSpan
a\startTrillSpan a
\once \override Rest #'transparent = ##t
r\stopTrillSpan

To Mr. Edward Neeman,
  Hi, thank you very much for your reply. The \override worked. However,
since you mentioned that this could be a bug, should I report it? (This
happened on both versions 2.6.3 and 2.7.12 that I tested)
Thanks.
Yours sincerely,
Seng Liang.
