Fair enough, I'm not wedded to that name. Search-and-replace is
still easy enough at this point ...

Hmm. The thing that's bothering me is that the length is the size
of the *destination*, which is not like cstring_to_text_with_len,
so using a closely similar name might be confusing. Of those two
I'd go with text_to_cstring_limit. Another thought that comes to
mind is

void text_to_cstring_buffer(const text *src, char *dst, size_t dst_len)

Anyone have other ideas?
