PATCH: Lyrics break estimation of vertical spacing

[Boris Shingarov]

Here is the patch for the "begin/rest-of-line" problem.
 (Sorry, couldn't upload to appspot for various reasons).
  
 I have also attached two score examples illustrating the bug.
We should probably augment the test suite, too, for the bug
to be considered done done.
 
Btw, how does one file a proper file report?
The bug tracker says scary things to the effect of "never create
a bug report directly in this tracker, or risk being permanently
killed; instead, write to the -bug maillist."  Well at least this is
my (mis-?)understanding of it.  I have written numeruos reports
here, but never actually saw it result in a tracked report.
What is the correct procedure?
