There are also some problems with your patch:
* It is a kludge (because of the guesswork for the notehead width, and
the manual entry)
* It changes the semantics of \property: it resets the value after
using it once. This is serious, because it means that it has to be
changed some time.
(I know that I'm guilty of this mistake as well, in a few places.
It is one the things I'll try to fix, some time.)
Your patch doesn't duplicate much, but I feel uncomfortable about
letting kludges enter the source code, especially if they're not mine
(Explanation: I have less problems with letting my own kludges enter
the code, because I know that I will be around to fix it when that
time has come. However, I usually end up being the guy that fixes
other's kludges as well. When I see a kludge authored by someone else,
I instinctively think about the time it will cost me to fix it.)
In any case, the following changes the issue:

Why don't we try to solve the problem completely? Sketch of the
solution:
* Build an engraver that catches noteheads and lyrics.
(It needs to be in a context above Staff and Lyrics, eg. in Score
context.)
* Determine which heads belong to which lyrics
(eg. by looking at the names of their originating contexts, or maybe
some \properties)
* Attach the lyrics to the appropriate heads
(by doing lyric->set_parent (head, X_AXIS), that will fix the current
noteheadwidth guessing kludge)
* Check if the lyric syllables end or start a phrase.
(eg. check if the syllable ends with punctuation, and remember that
fact for the next one.)
* Adjust their alignment accordingly.
(eg. by doing lyric->add_offset_callback(centered_on_parent,X_AXIS)
and setting self-alignment-X)
* Add a property to switch on/off the engraver (for multi stanza
vs. single stanza music)
Maybe this engraver could also take care of correct lyric alignment
for melismas as well.

I hope the above explains a better way doing it. If you want to try
implementing this, feel free to ask any further questions.
