Since 4aff646d17 (archive-zip: mark text files in archives,
2015-03-05), the zip archiver will look at the userdiff
driver to decide whether a file is text or binary. This
usually doesn't need to look any further than the attributes
themselves (e.g., "-diff", etc). But if the user defines a
custom driver like "diff=foo", we need to look at
"diff.foo.binary" in the config. Prior to this patch, we
didn't actually load it.

I'd be surprised if anybody actually triggered this in practice. I don't
think any of the custom-driver fields except "binary" matter, and using
direct attributes is almost always easier than setting up a custom
driver. Though you could also do trickery with:
git -c diff.default.binary=true archive ...
if you wanted to be really clever.
I ran across this while investigating a case where somebody's zipfile
was all marked as binary (it turned out not to be related; the issue was
just that their Git was pre-4aff646d17).
I also happened to notice that zipfiles are created using the local
timezone (because they have no notion of the timezone, so we have to
pick _something_). That's probably the least-terrible option, but it was
certainly surprising to me when I tried to bit-for-bit reproduce a
zipfile from GitHub on my local machine.
