\stemBoth

[Jean-marc LEGRAND]

Hi list !

Some weird behaviour under Lily 2.2 and XP.

I've just moved from Lily2.0 to 2.2, and \stemBoth doesn't seem to work the 
same way.

Here's my script :

tr = \markup {\musicglyph #"scripts-rcomma"}

basseI =    \notes
            \context Staff <<
            \new Voice {\voiceOne
            \time 4/4
            \key d \minor
                \clef alto
                \relative c' {

\stemUp f1
d2 c
bes a
b c
f f
e d
a a
\clef F
g f
e d
c bes
a f'
f4.^\tr e8 f2
\bar " "
\time 3/4}
\stemBoth f4 a8 bes c4
bes4.^\tr (a8) g4
a f2
g4.^\tr (f8) e4
f a c
\clef alto
d8 [e d c] bes [a]
(...)

\stemBoth doesn't work at all : all the stems are still up. On the other 
hand,when I specify
\stemDown, it does work fine.

Anyone knows why ?

Regards
