There's nothing in the documentation policy for \context block
formatting, but since you've amended some examples in the LM, I
thought I'd check what the preferred style should be to prevent
any
confusion.
I much prefer the context name to be on the next line (this is how
I've always edited snippets), so I'd like to propose the
following:
* blocks of code starting with an opening curly brace should be
followed by a newline unless a closing brace is encountered on the
same line, i.e.,
\context { \removeEmptyStaffContext }
\context {
\Foo
...
}
