should ignoreMelismata reset syllable left-alignment?

[Kieren MacMillan]

Hey, devs!

While helping a newbie on -user, I noticed that ignoreMelismata  
doesn't *actually* ignore melismas fully: in the attached example,  
you'll note that the "three" syllable is *left-aligned*, as it would  
be if it were *observing* melismata. Does anyone know what  
traditional/desired practice is?

It may be visually preferable as currently implemented... I'm just  
trying to make sure that Lilypond is actually outputing the  
*intended* result!  ;)

Cheers,
Kieren.
