this also looks a little suspect:
Real total_head_length = previous_extents[d].length ()

As for Keith's code:
{ \time 4/1
\override Score.SpacingSpanner #'packed-spacing = ##t
c'1 a <b'' c'''> <g''' a'''> }
I can see no too much spacing between b'' and c''', and g''' and a'''
The notes within the chords are spaced normally, but the chords are too-far
separated from each other. It is only a tiny problem. No-one reported
noticing the problem in output, only in the code.
Was that bug already filed or should I do it?
It is so closely related to
http://code.google.com/p/lilypond/issues/detail?id=2493
that I'll just add a note there.
Anyway, I don't understand: "The cause seems to be the decision
to scale the ledger from the notecolumn width,
I should have set "to scale the rod...". The function set_rods() at
<http://codereview.appspot.com/6109046/diff/6001/lily/ledger-line-spanner.cc#newcode39>
is passed two columns and asked to figure out the space needed for ledgers.
Now I see that the extents passed to set_rods() include /only/ notes that go on
ledgers, so finally I see how HanWen's original suggestion should work.
And where to find what's min_length_fraction for?
It is a local variable holding the last parameter to set_rods() so you have to look at how
set_rods() is called, and figure out how that last parameter is determined. It comes from
some property of a Ledger_line_spanner called "minimum-length-fraction" that might be
talked about <http://lilypond.org/doc/v2.14/Documentation/internals/ledgerlinespanner>
Take a look at:
{ \time 4/1
\override Score.SpacingSpanner #'packed-spacing = ##t
c '1 b a <b' e''> c '1 b a <b' c''> }
Shouldn't b'/c'' be to the right of the note a,
Packed spacing means space tight as possible, so I do not worry that the chords
overlap. The overlap is not confusing when there are stems.
