Beam subdivision and fingering in tablatures

[Sebastiano Vigna]

Two questions (I posed one in lilypond-devel, not realising it was the
wrong place):

1) Is there any way of forcing a beam subdivision at a certain point? I
am typesetting drum scores, and whem I have things like

sn32[ sn sn sn sn sn sn sn]

I would like to force a one-line beam between the first and the second
group of four notes, as usual. However, using the automatic beam
subdivision does not work, because it subdivides also tuplets (e.g., 6-
tuplets). 

Moreover, beam subdivision in drum scores does not typeset the one-line
beam in the example above.

2) Is fingering in tablatures supported? I have tried with the same
method suggested for standard scores, but sometimes fingerings appear,
and sometimes not, rather randomly. Is this a bug or a lack of
implementation?
