As I said, I don't have the source code for `insert-file-contents', so I don't
know what it does. Why does `mm-i-f-c' redefine `default-value' locally?
If `auto-mode-alist' is not used by `i-f-c', and file-local variables are not
used, then how would a mode other than fundamental be used by it?
I was gathering, from the `mm-i-f-c' code and doc, that `i-f-c' did _not_
protect these things. And unfortunately the doc for `i-f-c' says nothing about
any of these things specifically - unlike the doc of `mm-i-f-c'. Who knows what
`i-f-c' does or does not do, and how it is really different from `mm-i-f-c'?

So why does `mm-i-f-c' make sure to bind it to ()?

What is "this"? `after-insert-file-functions'? Or binding that to ()? If the
latter, then I guess I need such a binding.
The doc for `mm-i-f-c' says that it does code conversion, which I understood to
include decoding. Doesn't that mean that this is not done via
`after-insert-file-functions', since that is bound to ()?

What/where? What does `i-f-c' do wrt `enable-local-eval'?

What is the bug? Are you saying that `mm-i-f-c' should not include such a
binding?
In my case, I do not really want remote file handlers to kick in.
What does `i-f-c' do wrt remote files? For a workhorse function, its doc seems
quite paltry. About the only thing it is specific about is code conversion.

OK.
It's still not at all clear to me which I should use, I'm afraid. Starting with
the obvious question: Why, if `i-f-c' does all of what you say, are those
bindings needed in `mm-i-f-c'? And why does the `mm-i-f-c' doc make a point of
saying that it acts differently in regard to these particular things than does
`i-f-c'? You seem to be saying that they act the same (?).
Let me be clear: I am not arguing about what the case is or isn't - I'm not
arguing at all. I'm just asking, to learn, and (still) wondering what I should
use.
