Heh, questions that I can actually answer with confidence... ;-) Yes, it's the 
current state.

For the "la" on 4, there actually is no melisma - the corresponding note is 
only the e''4. (Note that both lyric lines are assigned to the *middle* voice; 
the first and third staff just contain noise that has nothing to do at all with 
the lyrics.) Hence, the superfluous stub extender is removed.

W.r.t. the graces, classical notation rules demand that syllables are not 
printed below grace notes, but on the main note. I agree that's strange, but 
that's how it is according to the old school - use your favorite search engine 
with "lilypond lyrics grace notes" to find samples. There's an 
includeGraceNotes property to adjust that, but it's not in use in this regtest.
However, and here it becomes really ridiculous, even with the old version you 
were supposed to start the third "da" already on the graces. So the extender 
over the graces used to be extremely misleading, if not plainly wrong. This 
behavior is configurable (which makes sense if there would be no rest, and the 
previous syllable should last over the graces).

And yes, we do have so little relevant examples. We hardly have melismata with 
lyrics in regtests, and if so, then extenders have been added explicitly to 
provide a visual cue whether the melisma is recognized.

Actually, this is a content vs. presentation issue. The current approach has 
lyric extenders ‘hardcoded’ within the lyricmode input, whereas often it 
depends on layout whether I want an extender printed or not:
– In tight horizontal spacing, we might not need an extender, but when spacing 
is stretched, it might become necessary. This can come through different 
\(page/line\) breaking, parallel contexts present only in some editions \(part 
vs. score\), Completion\_heads\_engraver \(mensural without 
barlines/transcription with barlines\).
– Long syllables might not need an extender, where short syllables do.
– Often, all voices share the same text, but have extenders in different 
places. If extenders need not be given explicitly, the lyricmode input code can 
be reused much easier.

After all, the extenders don’t add any additional meaning, but only serve to 
improve legibility in such cases where they do.

This would require: 
– Recognising the end of a word by absence of a hyphen.
– Comparing printed length of the melisma notes vs. the syllable, likely after 
line breaking. After all, extenders will never influence horizontal spacing. 
They might, however, affect vertical spacing. \(unless we chose to omit \(or 
shift\) the extender in that case?\)
– Personally, I think very short extenders shouldn’t be printed. There should 
be some kind of threshold.
It’s also one of the usecases where a proper representation of a ‘lyric word’ 
would be helpful, along with [issue 2458](#2458).

[Version 
2.12](http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Aligning-lyrics-to-a-melody#Multiple-notes-to-one-syllable)
 had this listed as a Known issue.
