Emitting whitespaces in the parser is a bit annoying and fragile, but
it can be done.

We post-process the parser output with `indent` internally. We could
run it after the output is produced, but that would mean a new
dependency.

I'd go for opportunistic indentation through `indent` if installed.

Yes, see `gen_idef_parser_funcs.py`.
