Thank you, Lars. I can't believe it didn't occur to me earlier.

I'd put "elisp" or somesuch in the name, to make it clear it's about
generation of ELisp files rather than generation of any other kinds

I suggest to use names that make it more clear which of the two should
be a single line. Maybe `title` and `commentary`?

Why would we ever want to not insert `Code:`?
More importantly, I think this function needs an additional (and
mandatory!) argument, which specifies which function generated it.
I've too often wasted time locating the code responsible for a bug in
the generated file just because that file failed to tell me where this
generated file comes from, so we should make it "harder" to generate
a file without that origin information.

Hmm... this makes the function unusable for third party packages,
