Comment #5 on issue 1702 by address@hidden: Unaesthetic beam slope
http://code.google.com/p/lilypond/issues/detail?id=1702

The old behavior of 2.12 regarding the beam slope was *very* accidental.
(Apply \transpose e c and you find that 2.12 produces a steep beam like 2.14.)

The old spacing system gave the StaffSymbol an extent of (-4 . 4), which is two spaces beyond the drawn staff-lines, so Lilypond spread the staves to keep the sharp on the fis at least two spaces clear of the upper staff. If we tell version 2.14 to
  \override StaffSymbol #'minimum-Y-extent = #'(-3.5 . 3.5)
then it spreads staves like 2.12 did ...
but the some ledger lines disappear due to some intervening change. (Bummer. I liked having extra clearance to the foreign staff itself, more than the clearance to a dynamic mark attached to the foreign staff. By Mike's rule I guess that's a bug.)

Workarounds are to increase staff spacing when we want to force unusual kneed beams :

\new PianoStaff \with {
  \override StaffGrouper #'staff-staff-spacing #'basic-distance = #10.5
  % or alternatively,
  %\override StaffGrouper #'staff-staff-spacing #'padding = #2.5
}
