Question about melismatic note warning

[r . alverny]

Hi there,

I am starting using Lilypond for typesetting some songs, and I really
find this tool mar-ve-lous. Many thanks to the authors and contributors.

I am best at learning by example, and thus have two questions.

First.
I am working on Mozart Ave Verum for Mutopia (4 voices choral with
lyrics, and multi-voices organ).
I am done with the choral part now, and the result is correct,
but I still have severals

avertissement: Huh? Melismatic note found to have associated lyrics.

lines when processing my file.
I did not find some explanation about that, and wanted to have some
advice here..?
The actual message I get is the following (corresponding the code
excerpt below):

Interpreting music...[8]
avertissement: Huh? Melismatic note found to have associated lyrics.
[16][24]
avertissement: Huh? Melismatic note found to have associated lyrics.
 
avertissement: Huh? Melismatic note found to have associated lyrics.
 
avertissement: Huh? Melismatic note found to have associated lyrics.
[32]


Second (this one may help the first one).
Here is included an excerpt of my Ave Verum thing; being a beginner,
I would like some "best practice" advice (if there is any), or some
"clean and standard readable way of coding" tips.
It is just a way to get things working correctly for basic usage,
and then dive into the details.

Many thanks.
