updating `\relative {' in source?

[Mark Polesky]

Since \relative { ... } is deprecated, I presume we should
update all the non-compliant instances in the source (adding
a "c" between "\relative" and "{" ?

I didn't want to rush into a sed command too quickly because
I'm always hazy on the snippets and regression tests WRT
auto-generated code.  Here's what I found:


$ regex='\\relative @\?{'

$ git grep "$regex" | wc -l
111

$ git grep "$regex" input/regression/* | wc -l
67

$ git grep "$regex" Documentation/* | wc -l
41

$ git grep "$regex" scripts/* | wc -l
2

$ git grep "$regex" lily/* | wc -l
1


Which of these can I add a "c" to, and which should I leave
alone?
