Well, it's done by ZLE when ZLE is active, which it isn't always.

However, I think what you're looking for is Src/Zle/zle_main.c in the
Nuts! I never even thought to look in a subdir. No wonder all trails went cold.
function zle_main_entry() under "case ZLE_CMD_READ" where the call to
zleread() is made.  Or perhaps where that's called, which is usually
from Src/input.c:inputline() via zleentry(ZLE_CMD_READ, ...).

} ... I'm hoping there will be some_string somewhere such that:
}     puts(some_string)
} ... will print exactly:
}     some-command $1 *.* !{1, 1 & @ >>! $2 "no parsing please!" .. ()
} '<<' `# ^ -n(*&<)` {}

No, that there isn't, though if you look around line 296 of input.c where
the VERBOSE option is handled, you'll get close.  The input line is read
into what's called "metafied" form by zleread() and has to be unmetafied
[by the aptly named function unmetafy(), Src/utils.c] to return it to
the raw input form.
But. But ... we can't get the string before it's metafied in the first place? How is it possible for it to be metafied before 'it' exists? If I can have a meta-fried egg, surely at some point there was a raw egg? I was looking in hist.c, because the one place where things seem to be
stored 'literally' is in .histfile.

The Tao of zsh is a deep thing.

But somehow I just can't get anything to print if interactive. I've got lots of feedback if adding " puts("Hi. This is line xxx of file xxx") " ... sort of things in the code
when  running a script, but if interactive nothing ever shows:

//    if (isset(VERBOSE)) {
    /* Output the whole line read so far. */
    zputs(ingetcline, stderr);
 //   }

... nothing doing, no output. I tried it from console too. Nothing. Is the xterm somehow
