In the current code, callers are expected to fill in the
pretty_print_context, and then the pretty.c functions simply
read from it. This leaves no room for the pretty.c functions
to communicate with each other by manipulating the context
(e.g., data seen while printing the header may impact how we
print the body).
Rather than introduce a new struct to hold modifiable data,
let's just drop the const-ness of the existing context
struct.
