Bar line placement fails to account for long lyrics

[Daniel Poon]

\version "2.10.25"

%{
%% Long lyrics extend across bar lines inappropriately.
%% Distance between bar lines ought to take lyric length into account.
%% Lyrics should also be left-justified to a space before the corresponding
note, not centered upon the note.

%{
 What one would expect from a human engraver is for the measures containing the
very long lyrics to be appropriately expanded.  A syllable of lyric text would
generally be left-justified to a space slightly to the left of the note to which
the text corresponds.

Lilypond currently disregards the very long lyric: though it handles text-text
collisions well by positioning notes, it does not account for the size of the
lyric text when positioning bars.  The lyric text is then placed below the
staff, X-centered upon the note to which it corresponds, which often makes it
protrude beyond the bar.
