This is OK, thanks!
I've noticed couple of things that might still be cleaned up somewhat,
but this can be done as a follow-up patch (if at all):
- As all the top-level val_print callers set deref_ref to 1, maybe the
default user_print_options should have that value, making most (all?)
of the explicit opts.deref_ref = 1 statements obsolete.
- Maybe the "size" argument (to the print_formatted routines) should
also move into the struct, together with "format"?
- In some cases (e.g. print_subexp_standard) you have multiple instances
within the same function where a local "opts" variable is created;
maybe it would be clearer to have a common "opts" initialized once
for the whole function?
Bye,
Ulrich
