Bug/feature/help? with extenders

[Phil Holmes]

I've been setting some music where one verse ends with some music and 
lyrics, and the others don't.  All 4 verses use underscore extenders to 
provide a line to the end of the sounding note.  This works fine on the 
first verse, since there are lyrics after the underscores, but it doesn't 
work as I want on the other verses.  I've made a shorter version of the 
problem to illustrate it - .ly snippets are available, but I think just the 
PDF and lyrics show it well enough.

In UnderscoreTest.pdf I've put an extra syllable after the extender, and 
this now ends where it should.  The lyrics for the second verse are:

{ La la la __ La la la __ La }

In UnderscoreTestShortError.pdf there's no lyric syllable after the 
extender, and the extender now reaches the following note, which I believe 
it shouldn't do.  The lyrics are:

{ La la la __ La la la __ }

This is a particular problem when there's a lot of blank space between the 
extender and the final notes - the extender becomes very long and throws an 
error when it crosses a line break.

Is this a bug or just something I'm doing wrong?

(BTW - I do know how to work around this by using \once \override LyricText 
#'stencil = ##f and placing some dummy lyrics at the end, but would prefer 
to avoid this if possible).
