Re: BUG OR FEATURE?: \markup { "Piano " } vs. \markup { "Piano" " " " " }

[Mats Bengtsson]

I have just changed the text in the bug description in the manual to say:

When you put a name on a grand staff or piano staff, the width of the
brace is not taken into account. The following property setting can be
used to move the instrument names to the left, in such situations.
@example
\override Score.InstrumentName #'space-alist = #'((left-edge extra-space 
. 2.0))
@end example

On the other hand, why not increase the default spacing from 1.0 to 2.0
to avoid these collisions. I don't think that it looks too wide even
when you don't have any starting brace/bracket. Also, I think there
is a sufficiently large number of pieces for piano + one or more
instruments so the problem appears often enough now.
