Comment #5 on issue 2738 by [email protected]: Lilypond doesn't break lines http://code.google.com/p/lilypond/issues/detail?id=2738
I would suggest that Lilypond to print a clue to STDERR at the end of processing. Something, like:
"Could not break line in one or more places, because of note length goes beyond a bar. Please, consider 'Forbid_line_break_engraver'".
That should help people to save time.
