Fix extra spacing in Kievan notation

Fix extra spacing in Kievan notation

In Kievan notation, notes should be spaced as tightly as possible within melismas.

This patch fixes extra spacing caused by long syllables.

Issue 2631.

Please review.

I don't like that: the patch manipulates a staff based on note head.  it also
increments a hack.

have you tried something like
\override SpacingSpanner #'shortest-duration-space = #0
\override SpacingSpanner #'spacing-increment = #0
?

The presence of a long syllable in the lyrics makes the left_col->extent larger
than spring.min_distance(). Manipulating the SpacingSpanner properties has no
effect -- the extraneous space is still there.

long syllables are a general problem, see Janek's GSoC list, it shouldn't
be solved this way.

The GSoC issues do not deal with packed spacing, so this is somewhat different,
though related. Do you have any ideas for how this issue could be addressed
differently? Has there been any work on the various GSoC issues?

Yes, and it waits to be merged to master.  Unfortunately, some things
need considerable discussion before merging, and i'm very short on
time :(
