Looking at that file, it does contain queries that look for ERROR nodes, 
e.g.

(
   ERROR
     "for" "(" @indent.begin ";" ";" ")" @indent.end)

So perhaps we should revisit that approach too.

We could do an indent implementation that just uses these indents.scm 
files. Not exactly sure why we didn't start out this way, but note that 
our Lisp based solution is a lot more flexible.

E.g. there doesn't seem to be an obvious way to support "indentation 
styles" with these.
