suggestion for LM 5.1.3

[Andrew Hawryluk]

Under LM 5.1.3 "Large projects" could we include something like this?
It might also fit under 5.1.4 "Saving typing with variables and
functions". Either way, I didn't discover this simple idea until I was
browsing through the mailing list, and it would have saved me some
trouble. (I was adding rehearsal marks to each instrument's music
variable. How embarrassing!)

In large projects, you can combine several reusable variables to make
a single staff of music. For example, if three trumpet lines have the
same dynamics we could create a single variable that holds only the
dynamic indications separated by skips. Likewise, if rehearsal marks
are needed, they will be the same for all instruments.

trumpetdynamics = { s1\f s1*10 s1\mp }
rehearsalmarks = {s8 \mark \default }
...
\score { <<
    \new Staff { << \firsttrumpetnotes \trumpetdynamics \rehearsalmarks >> }
    \new Staff { << \secondtrumpetnotes \trumpetdynamics \rehearsalmarks >> }
>> }
