Hmm. Maybe the rule should be "Always use { } in conjuction with
a \new or \context "? or maybe "Always use { }, even if they
aren't required, other than the ones that would surround the
entire example if we didn't use the [fragment] option" ?
Trouble is, I'm not certain which commands we require the {} for,
in addition to \new and \context, but I have the feeling there
were a few. I mean, given an example, I could unambiguously state
them... oh, hey, there's \relative and \transpose as well... but
I'm not confident in giving the entire list.
I think the "always add explicit {} apart from ones that would
surround an entire example" might the best way to go; if we
encounter any more exceptions to the "always use them" rule, we
can add them later.
Cheers,
